Blog/Table problem

I’m doing a beta test for a blog (https://www.creepysites.com/betatest). I”m using Dreamweaver and integrating my wordpress blog through that. My problem is that i want to have the blog table adjust to the size of the blog. As you can see by looking at the page, you have to scroll down on the blog as well as on the side of the page. I would like it if you only had to scroll down on the side of the page, and for the table to automatically adjust to the size of the blog. Is there any way of doing this? Thanks.
