Thanks Zentara!!! I have tried the above approach, but not working. try the code below.

use strict; 
use warnings; 

use Tk; 
use Tk::Table; 
use Tk::Pane; 

use constant COLUMNS => 5;

my $mw = MainWindow->new(); 

$mw -> resizable (0,0);
$mw -> geometry ("+10+10");
$mw -> geometry ("750x500");

my $spane = $mw->Scrolled('Pane',
        -scrollbars => 'oe', -bg => "orange"
         )->pack(-expand => 1, -fill => 'both');
     
#my $yscrollbar = $spane->Subwidget('yscrollbar');
#$yscrollbar->focus;

my $local_title = $mw->title ("perl: New File");     

my $basic_label = $spane->Label (
    -text => "Old Names",
    -font => "verdanafont 10 bold",
