Hello monks

I am taking columns from a csv file , now I don't have the exact number of columns so I wish to use Double dimension array

so here is what I am doing

 
sub column_segregation
{
    
    my ($file,$col) = @_;
    use Text::CSV;
        
  my @array_A2 = ();
  open my $io,'<',$file or die "$!";
  my $csv = Text::CSV->new ({ binary => 1 });
  while (my $row = $csv->getline($io)) {
    push @array_A2, $row->[$col];
  }
  close $io;
  return (@array_A2);                                 

}

so this routine will return an array , now i want each column should go to each corresponding column in Double dimension array. i.e. column 1 should go to column of 1 DD array and so on .

So I have never worked with DD array so how to put it in the DD array column is what I need help with <\n>
