Table making sidebars disappear

I am using tables for the content on three pages of my blog. Sidebars are showing up correctly on two of those pages, but on the third they have disappeared completely. When I delete my post content, the sidebars appear again on the page.

I cannot find what is causing this problem. Can someone please look at my page source and tell me what the source of the problem is?
