I often use Template::Toolkit for this type of problem.

You may find it overkill to include such a large module with several dependencies if you're only writing a small script that you want to distribute widely. If I write something for personal or proprietary commercial use, I know that any system I use will already have TT installed.

For outputting a text table, see Template::Plugin::Filter's format method, and maybe the length virtual method if you want to resize the table according to the text displayed, or the truncate filter if you don't.
