NAME

       Tk::Table - Scrollable 2 dimensional table of Tk widgets

SYNOPSIS

         use Tk::Table;

         $table = $parent->Table(-rows => number,
                                 -columns => number,
                                 -scrollbars => anchor,
                                 -fixedrows => number,
                                 -fixedcolumns => number,
                                 -takefocus => boolean);

         $widget = $table->Button(...);

         $old = $table->put($row,$col,$widget);
         $old = $table->put($row,$col,"Text");  # simple Label
         $widget = $table->get($row,$col);

         $cols = $table->totalColumns;
         $rows = $table->totalRows;

         $table->see($widget);
         $table->see($row,$col);

         ($row,$col) = $table->Posn($widget);

DESCRIPTION

       Tk::Table is an all-perl widget/geometry manager which allows a two dimensional table of arbitrary
       perl/Tk widgets to be displayed.

       Entries in the Table are simply ordinary perl/Tk widgets. They should be created with the Table as their
       parent. Widgets are positioned in the table using:

        $table->put($row,$col,$widget)

       If $widget is not a reference it is treated as a string, and a Lable widget is created with the string as
       its text.

       All the widgets in each column are set to the same width - the requested width of the widest widget in
       the column.  Likewise, all the widgets in each row are set to the same height - the requested height of
       the tallest widget in the column.

       A number of rows and/or columns can be marked as 'fixed' - and so can serve as 'headings' for the
       remainder the rows which are scrollable.

       The requested size of the table as a whole is such that the number of rows specified by -rows (default
       10), and number of columns specified by -columns (default 10) can be displayed.

       If the Table is told it can take the keyboard focus then cursor and scroll keys scroll the displayed
       widgets.

       "-scrollbars". By default, scrollbars will be added "nw".  To disable scrollbars, set "-scrollbars" to an
       empty string:

         $table = $parent->Table(-scrollbars => '', ...);

       The table can be emptied using

        $table->clear

       the widgets which were in the table are destroyed.

       The Tk::Table widget is derived from a Tk::Frame, so inherits all its configure options.

       The default focus traversal is giving the focus only to the table widget as a whole. To enable focus
       traversal into table cells (e.g. if there are embedded entry widgets), then the option "-takefocus" has
       to be set to 0.

BUGS / Snags / Possible enhancements

       •   Very large Tables consume a lot of X windows.

       •   No equivalent of pack's -anchor/-pad etc. options
