Why is my product page cut off in Debut Theme?

I’m not sure why it’s doing this. Maybe it’s the way the theme is setup. But I would like the margins to extend further out so that the table will show and the tabs will all be on one line. Can someone show me how I can do this? The website is www.merakaiofficial.com

Hello There,

it’s working fine

So it is not cut off as I originally thought, but rather when going to the “Size Guide” tab, I have to use the scrollbar to view the entire table. I would like it t show the entire table without having to scroll as well as having the tabs on one line.
