NAME

       LaTeX::Table - Perl extension for the automatic generation of LaTeX tables.

VERSION

       This document describes LaTeX::Table version 1.0.6

SYNOPSIS

         use LaTeX::Table;
         use Number::Format qw(:subs);  # use mighty CPAN to format values

         my $header = [
             [ 'Item:2c', '' ],
             [ '\cmidrule(r){1-2}' ],
             [ 'Animal', 'Description', 'Price' ],
         ];

         my $data = [
             [ 'Gnat',      'per gram', '13.65'   ],
             [ '',          'each',      '0.0173' ],
             [ 'Gnu',       'stuffed',  '92.59'   ],
             [ 'Emu',       'stuffed',  '33.33'   ],
             [ 'Armadillo', 'frozen',    '8.99'   ],
         ];

         my $table = LaTeX::Table->new(
               {
               filename    => 'prices.tex',
               maincaption => 'Price List',
               caption     => 'Try our special offer today!',
               label       => 'table:prices',
               position    => 'tbp',
               header      => $header,
               data        => $data,
               }
         );

         # write LaTeX code in prices.tex
         $table->generate();

         # callback functions help you to format values easily (as
         # a great alternative to LaTeX packages like rccol)
         #
         # Here, the first colum and the header is printed in upper
         # case and the third colum is formatted with format_price()
         $table->set_callback(sub {
              my ($row, $col, $value, $is_header ) = @_;
              if ($col == 0 || $is_header) {
                  $value = uc $value;
              }
              elsif ($col == 2 && !$is_header) {
                  $value = format_price($value, 2, '');
              }
              return $value;
         });

         print $table->generate_string();

       Now in your LaTeX document:

         \documentclass{article}

         % for multi-page tables (xtab or longtable)
         \usepackage{xtab}
         %\usepackage{longtable}

         % for publication quality tables (Meyrin theme, the default)
         \usepackage{booktabs}
         % for the NYC theme
         \usepackage{array}
         \usepackage{colortbl}
         \usepackage{xcolor}

         \begin{document}
         \input{prices}
         \end{document}

DESCRIPTION

       LaTeX makes professional typesetting easy. Unfortunately, this is not entirely true for
       tables and the standard LaTeX table macros have a rather limited functionality. This
       module supports many CTAN packages and hides the complexity of using them behind an easy
       and intuitive API.

FEATURES

       This module supports multi-page tables via the "xtab" or the "longtable" package.  For
       publication quality tables, it uses the "booktabs" package. It also supports the
       "tabularx" and "tabulary" packages for nicer fixed-width tables.  Furthermore, it supports
       the "colortbl" package for colored tables optimized for presentations. The powerful new
       "ctable" package is supported and especially recommended when footnotes are needed.
       "LaTeX::Table" ships with some predefined, good looking "THEMES". The program ltpretty
       makes it possible to use this module from within a text editor.

INTERFACE

       "my $table = LaTeX::Table->new($arg_ref)"
           Constructs a "LaTeX::Table" object. The parameter is an hash reference with options
           (see below).

       "$table->generate()"
           Generates the LaTeX table code. The generated LaTeX table can be included in a LaTeX
           document with the "\input" command:

             % include prices.tex, generated by LaTeX::Table
             \input{prices}

       "$table->generate_string()"
           Same as generate() but instead of creating a LaTeX file, this returns the LaTeX code
           as string.

             my $latexcode = $table->generate_string();

       "$table->get_available_themes()"
           Returns an hash reference to all available themes.  See "THEMES" for details.

             for my $theme ( keys %{ $table->get_available_themes } ) {
               ...
             }

       "$table->search_path( add => "MyThemes" );"
           "LaTeX::Table" will search under the "LaTeX::Table::Themes::" namespace for themes.
           You can add here an additional search path. Inherited from Module::Pluggable.

OPTIONS

       Options can be defined in the constructor hash reference or with the setter
       "set_optionname". Additionally, getters of the form "get_optionname" are created.

   BASIC OPTIONS
       "filename"
           The name of the LaTeX output file. Default is 'latextable.tex'.

       "type"
           Can be 'std' (default) for standard LaTeX tables, 'ctable' for tables using the
           "ctable" package or 'xtab' and 'longtable' for multi-page tables (requires the "xtab"
           and "longtable" LaTeX packages, respectively).

       "header"
           The header. It is a reference to an array (the rows) of array references (the
           columns).

             $table->set_header([ [ 'Animal', 'Price' ] ]);

           will produce following header:

             +--------+-------+
             | Animal | Price |
             +--------+-------+

           Here an example for a multirow header:

             $table->set_header([ [ 'Animal', 'Price' ], ['', '(roughly)' ] ]);

           This code will produce this header:

             +--------+-----------+
             | Animal |   Price   |
             |        | (roughly) |
             +--------+-----------+

           Single column rows that start with a backslash are treated as LaTeX commands and are
           not further formatted. So,

             my $header = [
                 [ 'Item:2c', '' ],
                 ['\cmidrule{1-2}'],
                 [ 'Animal', 'Description', 'Price' ]
             ];

           will produce following LaTeX code in the Zurich theme:

             \multicolumn{2}{c}{\textbf{Item}} &                                          \\
             \cmidrule{1-2}
             \textbf{Animal}                   & \multicolumn{1}{c}{\textbf{Description}} & \multicolumn{1}{c}{\textbf{Price}}\\

           Note that there is no "\multicolumn", "\textbf" or "\\" added to the second row.

       "data"
           The data. Once again a reference to an array (rows) of array references (columns).

             $table->set_data([ [ 'Gnu', '92.59' ], [ 'Emu', '33.33' ] ]);

           And you will get a table like this:

             +-------+---------+
             | Gnu   |   92.59 |
             | Emu   |   33.33 |
             +-------+---------+

           An empty column array will produce a horizontal rule (line):

             $table->set_data([ [ 'Gnu', '92.59' ], [], [ 'Emu', '33.33' ] ]);

           Now you will get such a table:

             +-------+---------+
             | Gnu   |   92.59 |
             +-------+---------+
             | Emu   |   33.33 |
             +-------+---------+

           This works also in "header".

           Single column rows starting with a backslash are again printed without any formatting.
           So,

             $table->set_data([ [ 'Gnu', '92.59' ], ['\hline'], [ 'Emu', '33.33' ] ]);

           is equivalent to the example above (except that there always the correct rule command
           is used, i.e. "\midrule" vs. "\hline").

       "custom_template"
           The table types listed above use the Template toolkit internally. These type templates
           are very flexible and powerful, but you can also provide a custom template:

             # Returns the header and data formatted in LaTeX code. Nothing else.
             $table->set_custom_template('[% HEADER_CODE %][% DATA_CODE %]');

           See LaTeX::Table::Types::TypeI.

   FLOATING TABLES
       "environment"
           If get_environment() returns a true value, then a floating environment will be
           generated. For std tables, the default environment is 'table'. A true value different
           from '1' will be used as environment name. Default is 1 (use a 'table' environment).

           The non-floating xtab and longtable environments are mandatory (get_environment() must
           return a true value here) and support all options in this section except for
           "position".

           The ctable type automatically adds an environment when any of the following options
           are set.

       "caption"
           The caption of the table. Only generated if get_caption() returns a true value.
           Default is 0. Requires "environment".

       "caption_top"
           If get_caption_top() returns a true value, then the caption is placed above the table.
           To use the standard caption command ("\caption" in std and longtable, "\topcaption" in
           xtab) , use

             ...
             caption_top => 1,
             ...

           You can specify an alternative command here:

             ...
             caption_top => 'topcaption', # would require the topcapt package

           Or even multiple commands:

             caption_top =>
                '\setlength{\abovecaptionskip}{0pt}\setlength{\belowcaptionskip}{10pt}\caption',
             ...

           Default 0 (caption below the table) because the spacing in the standard LaTeX macros
           is optimized for bottom captions. At least for multi-page tables, however, top
           captions are highly recommended. You can use the "caption" LaTeX package to fix the
           spacing:

             \usepackage[tableposition=top]{caption}

       "maincaption"
           If get_maincaption() returns a true value, then this value will be displayed in the
           table listing ("\listoftables") and before the "caption". For example,

             maincaption => 'Price List',
             caption     => 'Try our special offer today!',

           will generate

             \caption[Price List]{Price List. Try our special offer today!}

           Themes can set the font family of the maincaption.

           Default 0. Requires "environment".

       "shortcaption"
           Same as "maincaption", but does not appear in the caption, only in the table listing.
           Default 0. Requires "environment".

       "continued"
           If true, then the table counter will be decremented by one and the "continuedmsg" is
           appended to the caption. Useful for splitting tables. Default 0.

             $table->set_continued(1);

       "continuedmsg"
           If get_continued() returns a true value, then this text is appended to the caption.
           Default '(continued)'.

       "center", "right", "left"
           Defines how the table is aligned in the available textwidth. Default is centered.
           Requires "environment". Only one of these options may return a true value.

             # don't generate any aligning code
             $table->set_center(0);
             ...
             # restore default
             $table->clear_center();

       "label"
           The label of the table. Only generated if get_label() returns a true value.  Default
           is 0. Requires "environment".

            $table->set_label('tbl:prices');

       "position"
           The position of the environment, e.g. 'tbp'. Only generated if get_position() returns
           a true value. Default 0. Requires "environment" and tables of "type" std or ctable.

       "sideways"
           Rotates the environment by 90 degrees. Default 0. For tables of "type" std and ctable,
           this requires the "rotating" LaTeX package, for xtab or longtable tables the "lscape"
           package.

            $table->set_sideways(1);

       "star"
           Use the starred versions of the environments, which place the float over two columns
           when the "twocolumn" option or the "\twocolumn" command is active.  Default 0.

            $table->set_star(1);

       "fontfamily"
           Valid values are 'rm' (Roman, serif), 'sf' (Sans-serif), 'tt' (Monospace or
           typewriter) and 0. Default is 0 (does not define a font family).  Requires
           "environment".

       "fontsize"
           Valid values are 'tiny', 'scriptsize', 'footnotesize', 'small', 'normal', 'large',
           'Large', 'LARGE', 'huge', 'Huge' and 0. Default is 0 (does not define a font size).
           Requires "environment".

   TABULAR ENVIRONMENT
       "custom_tabular_environment"
           If get_custom_tabular_environment() returns a true value, then this specified
           environment is used instead of the standard environments 'tabular' (std) 'longtable'
           (longtable) or 'xtabular' (xtab). For xtab tables, you can also use the 'mpxtabular'
           environment here if you need footnotes. See the documentation of the "xtab" package.

           See also the documentation of "width" below for cases when a width is specified.

       "coldef"
           The table column definition, e.g. 'lrcr' which would result in:

             \begin{tabular}{lrcr}
             ..

           If unset, "LaTeX::Table" tries to guess a good definition. Columns containing only
           numbers are right-justified, others left-justified. Columns with cells longer than 30
           characters are p (paragraph) columns of size '5cm' (X columns when the "tabularx", L
           when the "tabulary" package is selected).  These rules can be changed with
           set_coldef_strategy(). Default is 0 (guess good definition). The left-hand column, the
           stub, is normally excluded here and is always left aligned. See
           LaTeX::Table::Themes::ThemeI.

       "coldef_strategy"
           Controls the behavior of the "coldef" calculation when get_coldef() does not return a
           true value. It is a reference to a hash that contains regular expressions that define
           the types of the columns. For example, the standard types NUMBER and LONG are defined
           as:

             {
               NUMBER                =>
                  qr{\A\s*([+-]?)(?=\d|\.\d)\d*(\.\d*)?([Ee]([+-]?\d+))?\s*\z}xms,
               NUMBER_MUST_MATCH_ALL => 1,
               NUMBER_COL            => 'r',
               LONG                  => qr{\A\s*(?=\w+\s+\w+).{29,}?\S}xms,
               LONG_MUST_MATCH_ALL   => 0,
               LONG_COL              => 'p{5cm}',
               LONG_COL_X            => 'X',
               LONG_COL_Y            => 'L',
             };

           "TYPE => $regex"
               New types are defined with the regular expression $regex. All cells that match
               this regular expression have type TYPE. A cell can have multiple types. The name
               of a type is not allowed to contain underscores ("_").

           "TYPE_MUST_MATCH_ALL"
               This defines if whether a column has type TYPE when all cells are of type TYPE or
               at least one. Default is 1 ($regex must match all).

               Note that columns can have only one type. Types are applied alphabetically, so for
               example a LONG NUMBER column has as final type NUMBER.

           "TYPE_COL"
               The "coldef" attribute for TYPE columns. Required (no default value).

           "TYPE_COL_X", "TYPE_COL_Y"
               Same as "TYPE_COL" but for "tabularx" or "tabulary" tables. If undefined, the
               attribute defined in "TYPE_COL" is used.

           "DEFAULT_COL", "DEFAULT_COL_X", "DEFAULT_COL_Y"
               The "coldef" attribute for columns that do not match any specified type.  Default
               'l' (left-justified).

           "MISSING_VALUE => $regex"
               Column values that match the specified regular expression are omitted in the
               "coldef" calculation. Default is "qr{\A \s* \z}xms".

           Examples:

             # change standard types
             $table->set_coldef_strategy({
               NUMBER   => qr{\A \s* \d+ \s* \z}xms, # integers only
               LONG_COL => '>{\raggedright\arraybackslash}p{7cm}', # non-justified
             });

             # add new types (here: columns that contain only URLs)
             $table->set_coldef_strategy({
               URL     => qr{\A \s* http }xms,
               URL_COL => '>{\ttfamily}l',
             });

       "width"
           If get_width() returns a true value, then "LaTeX::Table" will use the starred version
           of the environment (e.g. "tabular*" or "xtabular*") and will add the specified width
           as second parameter. It will also add "@{\extracolsep{\fill}}" to the table column
           definition:

             # use 75% of textwidth
             $table->set_width('0.75\textwidth');

           This will produce following LaTeX code:

             \begin{tabular*}{0.75\textwidth}{l@{\extracolsep{\fill} ... }

           For tables of "type" std, it is also possible to use the "tabularx" and "tabulary"
           LaTeX packages (see "width_environment" below). The tables of type ctable
           automatically use the "tabularx" package. See also "width_environment" for how to use
           this feature with longtable.

       "width_environment"
           If get_width() (see above) returns a true value and table is of "type" std, then this
           option provides the possibility to add a custom tabular environment that supports a
           table width:

             \begin{environment}{width}{def}

           To use for example the one provided by the "tabularx" LaTeX package, write:

             # use the tabularx package (for a std table)
             $table->set_width('300pt');
             $table->set_width_environment('tabularx');

           Note this will not add "@{\extracolsep{\fill}}" and that this overwrites a
           "custom_tabular_environment".

           It is possible to use "tabularx" together with tables of type longtable.  In this
           case, you have to generate a file and then load the table with the "LTXtable" command
           ("ltxtable" package):

             $table = LaTeX::Table->new(
                 {   filename    => 'mylongtable.tex'
                     type        => 'longtable',
                     ...
                     width_environment => 'tabularx',
                 }
             );

           Then in LaTeX:

             \LTXtable{0.8\textwidth}{mylongtable}

           Note that we have to do the specification of the width in LaTeX.

           Default is 0 (see "width").

       "maxwidth"
           Only supported by tables of type ctable.

       "eor"
           String specifying the end of a row. Default is '\\'.

             $table->set_eor("\\\\[1em]");

           Callback functions (see below) can be used to manually set the eor after the last
           column. This is useful when some rows require different eor strings.

       "callback"
           If get_callback() returns a true value and the return value is a code reference, then
           this callback function will be called for every column in "header" and "data". The
           return value of this function is then printed instead of the column value.

           The passed arguments are $row, $col (both starting with 0), $value and $is_header.

             use LaTeX::Encode;
             use Number::Format qw(:subs);
             ...

             # rotate header (not the first column),
             # use LaTeX::Encode to encode LaTeX special characters,
             # format the third column with Format::Number (only the data)
             my $table = LaTeX::Table->new(
                 {   header   => $header,
                     data     => $data,
                     callback => sub {
                         my ( $row, $col, $value, $is_header ) = @_;
                         if ( $col != 0 && $is_header ) {
                               $value = '\begin{sideways}' . $value . '\end{sideways}';
                         }
                         elsif ( $col == 2 && !$is_header ) {
                             $value = format_price($value, 2, '');
                         }
                         else {
                             $value = latex_encode($value);
                         }
                         return $value;
                     },
                 }
             );

       "foottable"
           Only supported by tables of type "ctable". The footnote "\tnote" commands.  See the
           documentation of the "ctable" LaTeX package.

             $table->set_foottable('\tnote{footnotes are placed under the table}');

       "resizebox"
           If get_resizebox() returns a true value, then the resizebox command is used to resize
           the table. Takes as argument a reference to an array. The first element is the desired
           width. If a second element is not given, then the height is set to a value so that the
           aspect ratio is still the same. Requires the "graphicx" LaTeX package. Default 0.

             $table->set_resizebox([ '0.6\textwidth' ]);

             $table->set_resizebox([ '300pt', '200pt' ]);

   MULTI-PAGE TABLES
       "tableheadmsg"
           When get_caption_top() and get_tableheadmsg() both return true values, then additional
           captions are printed on the continued pages. Default caption text is 'Continued from
           previous page'.

       "tabletailmsg"
           Message at the end of a multi-page table. Default is 'Continued on next page'.  When
           using "caption_top", this is in most cases unnecessary and it is recommended to omit
           the tabletail (see below).

       "tabletail"
           Custom table tail. Default is multicolumn with the tabletailmsg (see above) right-
           justified.

             # don't add any tabletail code:
             $table->set_tabletail(q{});

       "tablelasttail"
           Same as "tabletail", but defines only the bottom of the last page ('lastfoot' in the
           "longtable" package). Default ''.

       "xentrystretch"
           Option for xtab. Play with this option if the number of rows per page is not optimal.
           Requires a number as parameter. Default is 0 (does not use this option).

             $table->set_xentrystretch(-0.1);

   THEMES
       "theme"
           The name of the theme. Default is Meyrin (requires "booktabs" LaTeX package).

           See LaTeX::Table::Themes::ThemeI how to define custom themes.

           The themes are defined in LaTeX::Table::Themes::Beamer,
           LaTeX::Table::Themes::Booktabs, LaTeX::Table::Themes::Classic,
           LaTeX::Table::Themes::Modern.

             $table->set_theme('Zurich');

       "predef_themes"
           All predefined themes. Getter only.

       "custom_themes"
           All custom themes. See LaTeX::Table::Themes::ThemeI.

       "columns_like_header"
           Takes as argument a reference to an array with column ids (again, starting with 0).
           These columns are formatted like header columns.

             # a "transposed" table ...
             my $table = LaTeX::Table->new(
                 {   data     => $data,
                     columns_like_header => [ 0 ], }
             );

MULTICOLUMNS

       Multicolumns are defined in LaTeX with "\multicolumn{$cols}{$alignment}{$text}". This
       module supports a simple shortcut of the format "$text:$cols$alignment". For example,
       "Item:2c" is equivalent to "\multicolumn{2}{c}{Item}". Note that vertical rules ("|") are
       automatically added here according the rules settings in the theme.  See
       LaTeX::Table::Themes::ThemeI. "LaTeX::Table" also uses this shortcut to determine the
       column ids. So in this example,

         my $data = [ [' \multicolumn{2}{c}{A}', 'B' ], [ 'C:2c', 'D' ] ];

       'B' would have an column id of 1 and 'D' 2 ('A' and 'C' both 0). This is important for
       callback functions and for the coldef calculation.  See "TABULAR ENVIRONMENT".

EXAMPLES

       See examples/examples.pdf in this distribution for a short tutorial that covers the main
       features of this module. See also the example application csv2pdf for an example of the
       common task of converting a CSV (or Excel) file to LaTeX or even PDF.

DIAGNOSTICS

       If you get a LaTeX error message, please check whether you have included all required
       packages. The packages we use are "array", "booktabs", "colortbl", "ctable", "graphicx",
       "longtable", "lscape", "rotating", "tabularx", "tabulary", "xcolor" and "xtab".

       "LaTeX::Table" may throw one of these errors:

       "IO error: Can't ..."
           In method generate(), it was not possible to write the LaTeX code to "filename".

       "Invalid usage of option ..."
           In method generate() or generate_string(). See the examples in this document and in
           examples/examples.pdf for the correct usage of this option.

       "Attribute (option) ... "
           In method new() or set_option(). You passed a wrong type to the option. See this
           document or examples/examples.pdf for the correct usage of this option.

CONFIGURATION AND ENVIRONMENT

       "LaTeX::Table" requires no configuration files or environment variables.

DEPENDENCIES

       Carp, Module::Pluggable, Moose, English, Scalar::Util, Template

BUGS AND LIMITATIONS

       The "width" option causes problems with themes using the "colortbl" package.  You may have
       to specify here the overhang arguments of the "\columcolor" commands manually. Patches are
       of course welcome.

       Problems with the "width" option are also known for tables of type longtable. You should
       use the "tabularx" package as described in the "width_environment" documentation.

       Please report any bugs or feature requests to "bug-latex-table@rt.cpan.org", or through
       the web interface at <http://rt.cpan.org>.
