I hope this code is of help...
A multi-dimensional array is built by making arrays of references to array. You don't get to the actual data until the last dimension.
Here I explicitly build a 2D structure, what is called an AoA (Array of Array). 
#!/usr/bin/perl
use strict;
use warnings;
use Data::Dump qw(pp);

my @row1 = qw(a b c);
my @row2 = qw(d e f);

my @AoA = (\@row1, \@row2);

pp \@AoA;
# [["a", "b", "c"], ["d", "e", "f"]]


foreach my $my_row_ref (@AoA)
{
    print "@$my_row_ref \n";
}

#a b c 
#d e f 

print "$AoA[1][1]\n";  #prints "e"

#print column1...

foreach my $my_row_ref (@AoA)
{
    print "$my_row_ref->[1] \n";
}

#b 
#e
