The Tk::Table is not a very feature rich widget. I don't think it was designed for expanding/shrinking individual cells, without causing a glitch somewhere else, like improper layout of whatever you were to put in the cell.

You may have luck, but maybe you should look at TableMatrix or TableMatrix::Spreadsheet.

For example: 

#!/usr/bin/perl
use warnings;
use strict;
use Tk;
use Tk::TableMatrix;

my $top = MainWindow->new;

my $arrayVar = {};

print "Filling Array...\n";
my ($rows,$cols) = (400, 10);
  foreach my $row  (0..($rows-1)){
     foreach my $col (0..($cols-1)){
       $arrayVar->{"$row,$col"} = "$row,$col";
   }
}

print "Creating Table...\n";
## Test out the use of a callback to define tags on rows and columns
sub colSub{
  my $col = shift;
   return "OddCol" if( $col > 0 && $col%2) ;
}

my $label = $top->Label(-text => "TableMatrix v2 Example");

my $t = $top->Scrolled('TableMatrix', -rows => $rows, -cols => $cols,
    -width => 6, -height => 6,
 -titlerows => 1, -titlecols => 1,
 -variable => $arrayVar,
 -coltagcommand => \&colSub,
 -colstretchmode => 'last',
 -rowstretchmode => 'last',
 -selectmode => 'extended',
 -selecttitles => 0,
 -drawmode => 'slow',
 -scrollbars=>'se'
 );


my $button = $top->Button( -text => "Exit", -command => sub{
$top->destroy});

# hideous Color definitions here:
$t->tagConfigure('OddCol', -bg => 'brown', -fg => 'pink');
$t->tagConfigure('title', -bg => 'red', -fg => 'blue', -relief => 'sun
+ken');
$t->tagConfigure('dis', -state => 'disabled');

my $i = -1;
my $first = $t->cget(-colorigin);

my $anchor;
foreach $anchor( qw/ n s e w nw ne sw se c /){
 $t->tagConfigure($anchor, -anchor => $anchor);
 $t->tagRow($anchor, ++$i);
 $t->set( "$i,$first",$anchor);
}

$top->fontCreate('courier', -family => 'courier', -size => 10);
$t->tagConfigure('s', -font => 'courier', -justify => 'center');

$t->colWidth( -2 => 8, -1 => 9, 0=> 12,  4=> 14);

$label->pack( -expand => 1, -fill => 'both');

$t->pack(-expand => 1, -fill => 'both');
$button->pack(-expand => 1, -fill => 'x');

Tk::MainLoop;
