I'm using this code for my table:

But the table is cut off from about column 11 onwards. I'm also using \usepackage{fullpage} because I need 1" inch margins. I've also tried using the pdflscape package, but as per this question that strategy is not successful either.


\documentclassand the appropriate packages so that those trying to help don't have to recreate it. – Jake Dec 06 '11 at 01:54pdflscapeandscriptsizefor font. Also\setlength{\tabcolsep}{3pt}. Worked with article class and does not look that bad. Sorry too busy to post a full answer. – yannisl Dec 11 '11 at 08:24
