Hi, see Need help finding which column/row the mouse cursor is over in Tk.... You might be able to get your current scrollbar position, then use $scrollbar->set(first, last); to adjust your new range. You may even be able to juggle the code in the -scrollcommand option, and use the -fixedrows and or -fixedcolumns options to select your range. Here is something that you could look at to start your mind working.

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

my $mw= tkinit;
#$mw->geometry("400x400+100+100");

my $table = $mw->Scrolled('Table', 
                        -rows =>2,
            -columns => 100,
                        -fixedrows => 2, #trick to hide scrollbars
                        -fixedcolumns => 5,
                        -scrollbars => 'soe',
            -takefocus => 1,)->pack(-fill=>'both',
                                          -expand=>1);
my %widgets;

for my $row(1..10){
   for my $col(1..100){

    $widgets{$row}{$col} = $table->Button(
               -text=> "$row - $col",
           -background => 'white',
           -command => sub{ do_me($row,$col) }
         );
           
    $table->put( $row,$col,$widgets{$row}{$col} );
  }
}

MainLoop;

sub do_me{
  my ($row, $col) = @_;
  print "$row $col\n";
}
