wiki themes tables printing

I've installed DrupalEd and created a group for our Science Department where they would like to put their curriculum in a wiki table. The table pasted from Microsoft Word, no problem at all, but when you publish it, it overlaps over the OG navigation on the right hand side of the page. Is there a way for me to turn of the OG navigation on this page?

I'm also thinking of adding the Printer Friendly Pages module so these folks can print this form. Anyone had any good/bad experiences there?

Thanks! - Alex
