It can definitely be changed to look fancier. I just created a really simple one, not being a very design-y person myself. I would like there to be a border and lines separating the columns/rows, at least, like the Wikipedia one.
I believe the text is actually the same as the Wikipedia one now. It's bold for the names, and if they're links then they're even more prominent. What more would you want done to the text?
Templates only allow wiki markup and HTML, not CSS, as far as I know. I don't think CSS is something users can edit. So I think these changes would need to be made right in the HTML.
