I was talking about the general font size on the wiki (not just tables), which I managed to fix before your latest reply. The wikia.css previously had #WikiArticle {font-size:...}, which was working pre-ucp. I changed that to .WikiArticle, now it's working again. Gotta admit I don't have much of a clue about CSS, most of the stuff in there I did ages ago, involving many hours of research and looking at other wikis.

The tables being stretched to full page width is fixed too, it was due to the browser. Got the answer for that on the talk page of the FullWidthOasis article.

Only remaining issue I see right now is getting the colour formatting back, I'll be looking at a bot like you suggested to replace bgcolor with inline css.

Thanks again for taking the time to help me, much appreciated :)
