just close your main table out, then put it in its own 100% width table. it should lay neatly under the table above it.
i highly recomend you download firefox if you don't have it. the site looks pretty bad in it. might just be a table cell you forgot to close or something.
i see you are currently working on it since there have been changes in the last hour, so i'm not going to view source since it might be something you're already working to do.
