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);

($row,$col) = $table->Posn($widget);
DESCRIPTION
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: - $table->put($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. - The Table will create and manage its own scrollbars if requested via
-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.
BUGS / Snags / Possible enhancements
o Very large Tables consume a lot of X windows.
o No equivalent of pack's -anchor/-pad etc. options
