I wanted to present one more solution that doesn't require array padding.

my @left  =   (  1, 2, 3, 4, 5 );
my @mid   = qw/  A  B  C  D  E /;
my @right = qw/ A3 F7 3B 35 EF /;

my $high = 0;
$high = ( $high > $_ ) ? $high : $_ foreach $#left, $#mid, $#right;
foreach my $idx ( 0 .. $high ) {
    local $, = "\t";
    print map { ( exists $_->[$idx] ) ?
                         $_->[$idx]   :
                         ''
               } \@left, \@mid, \@right;
}

This has the advantage of not adding useless padding to the end of your arrays. Plus it preserves the array, so you don't have to make a copy of it ahead of time.

Once again it's untested: buyer beware.
