The Problem:
I'm using TableMatrix to store some data and I need some of the cells to span rows. Everything works fine if I span rows in the middle of the table, but it breaks if I try to span a cell in the last column to the end of the table. When this happens the last row and column both disappear from the table.

The Example:
I worked for a while isolating the cause of the disappearing cells and here is a very simple example of the problem:

#!/usr/local/bin/perl5 -w # Use Perl 5 with warnings

# Simple TableMatrix Bug Example
# Using ActiveState Perl v5.6.1
# Build 628 

use strict;
use Tk;
use Tk::TableMatrix;

my $main = new MainWindow;
my $table = $main->TableMatrix()->pack( -side => 'top' );

# Description of the "spans" method from http://www.perldoc.com/cpan/T
+ableMatrix.html
# $table->spans(?index?, ?rows,cols, index, rows,cols, ...?) 

#$table->spans("0,8", "9,0");     # Works fine. Cell 0,8 spans down 10
+ rows of the table.
#$table->spans("0,9", "8,0");     # Works fine.  Cell 0,9 spans down 9
+ rows of the table.
$table->spans("0,9", "9,0");     # Table breaks.  Last row and column 
+disappear.

If anyone could test this on something other than ActiveState's build I'd appreciate it. I've downloaded the latest versions of Tk and TableMatrix as well.

Thanks Monks.
