Your problem is being caused by not closing your first div.

Pro-tip: avoid HTML in articles, and avoid inline styles. If divs were not used, and the styles were applied to the tables, this problem would not have arisen. Using classes would make the page a lot less cluttered, and problems easier to notice.
