Forum:Help-can't figure out wikitext for table classes

At genealogy wikia, we need to transfer many Wikipedia articles for historical individuals so that they may be converted into a form more suitable genealogical purposes. My main problem has been formatting differences created because our wikia doesn't have the same CSS class settings as WP.

I know how to look up the settings for WP, eg consulting wikipedia:MediaWiki:Monobook.css and hardcoding them in, but this is producing intimidating wikitext for novices. I was wondering what the procedure is for requesting CSS changes (eg- get consensus and have a bureaucrat request the change?). Thanks. ~  Ph l o x
