If you are going to start modifying rows and cols, you will be better off using a straight TableMatrix, and putting it in a Scrolled Pane. Test for inputs right away, if you want to wait till later to do it, pop up a dialog and ask. 
#!/usr/bin/perl
use warnings;
use strict;
use Tk;
require Tk::TableMatrix;
require Tk::Pane;

# usage programname rows cols

my ( $rows, $cols ) = @ARGV;

#Then you could test if anything passed:
if ( !defined $rows ) { $rows = 4 }
if ( !defined $cols ) { $cols = 4 }

my $mw = tkinit;
$mw->geometry('400x400');

my $tp = $mw->Scrolled('Pane',
                     -sticky => 'nw',
                    )->pack(
                          -fill   =>'both',
                          -expand => 1,
                         );

my $bf = $mw->Frame()->pack();

my $t = $tp->TableMatrix( -cols => $cols,
                          -rows => $rows,
                  )->pack(-fill   =>'both',
                          -expand => 1 );


$bf->Button(-text=> 'add column',
             -command=>sub{$t->packPropagate(1);
                           $t->insertCols(0,1);
                       $mw->update;
                       },
             )->pack(-side => 'left');

$bf->Button(-text=> 'add row',
             -command=>sub{$t->packPropagate(1);
                           $t->insertRows(0,1);
                           $mw->update;
                       },
             )->pack(-side => 'right');
