Tk::Table is an all-perl widget/geometry manager which allows a two dimensional
table of arbitary 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:


If I<$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.

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

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

The table can be emptied using


the widgets which were in the table are destroyed.

The Tk::Table widget is derived from a L<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 C<-takefocus> has
to be set to C<0>.
