Making the Page Template full width to fit Table

Hey Sakin, Quick question on this page: http://www.backpackingotc.com/top-10-countries/ How can I widen out the page to spread the table across the entire page? I tried adding custom CSS to the Tablepress plug in that I used but it had no effect. I asked the author of the Tablepress plugin and he verified that it was something wrong with the theme. Also, there are 8 errors in the CSS according to w3's validator: http://jigsaw.w3.org/css-validator/validator?uri=www.backpackingotc.com&profile=css3&usermedium=all&warning=1&vextwarning=&lang=e Should I be concerned?
