Licker, usually the themes which do that are referred to as "SEO-friendly" or something like that by their creators. It's something that can be done with any number of columns, but the 3-column versions are the ones I've seen most often. Here's
one version so you can see how it works.
I've never looked at the theme source code for the theme you mentioned, but as far as the code formatting goes, you should be able to reformat it so that it's easier for you to work with. Just make a copy of the page first and keep that to swap back in case the changing the formatting does screw things up somehow. I have a source format profile in my text editor which lets me look at all code formatted the way I like. Then I can always compact it before uploading if I want to make it hard for others to read.
