Hello, I made a small mistake in creating the columns. I have corrected that. Now I want to delete a particular column upon a press of a button on the window. Please see the attached code below. 


/usr/bin/perl
use Tk;
require "/home/kumar/personal/tk_perl/HListplus.pm";
require "/home/kumar/personal/tk_perl/MTree.pm";


my $mw = MainWindow->new();
my $frame = $mw->Frame()->pack();

my $tree = $frame->Scrolled(
                            'MTree',
                            -height => 20,
                            -width => 50,
                            -columns => 4,
                            -itemtype => 'text',
                            -header => 'true',
                            );



$tree->add(ROOT_ITEM_PATH, -itemtype => 'text', -text => 'Jobs for tes
+t');

$tree->header('create', 0 , -itemtype => 'text',-text => 'Cells',);

$tree->pack;
$tree->header('create', 1 , -text => 'ID');
$tree->header('create', 2 , -text => 'State');

                            
$frame->Button(-text => 'Delete col', -command => sub { $tree->header(
+'delete',2,-text=> 'State');})->pack;

MainLoop;
