I was going to hack up a couple of examples doing it the traditional way, however, I decided to take a quick peek in CPAN. Looks like you might be interested in Array::PrintCols (alt. link). There's a pretty clear example in the module's documentation.

Just goes to show that there have been a lot of people using Perl over the years and that they've added just about everything you need to CPAN. Repeat after me: CPAN is your friend. :-)

Update (for the reply): Forgive me, but I don't find that a very convincing excuse (especially when we have some fine tutorials that show how to install modules properly--and clearly.) Taken to the extreme, it's like saying..."Well, because some people are still using Perl versions older than 5.005_03, I won't distribute any code using CGI.pm." Which would be completely absurd, of course. While I've ranted on the topic from a different angle, I think someone else said it more eloquently. The bottom line is the same. Someone else has already done the hard work. Why reinvent the wheel?
