There are no tables on that page. Everything is either an absolutely positioned div, or a paragraph contained within an absolutely positioned div. The huge space is caused by your (INLINE) positioning of the apDiv12 -
<div id="apDiv12" style="position: absolute; left: 10px; top: 1016px; width: 994px; height: 1452px; z-index: 10">
I count 90 such absolutely positioned elements on your page, which could be the poster child for why one shouldn't use absolute positioning as a primary layout method (http://www.apptools.com/examples/pagelayout101.php). Just use your browser text size controls to increase the browser's display of text a couple of ticks and see what happens to your layout (in Safari I just use Command-+). Two ticks, and the contents have overlapped so much that the page becomes unreadable. I recognize it my be too late to inform you of this fundamental mistake in your approach on this page, but if I were you, I'd fix it. Who would ramp up the text size like this? Anyone with vision problems who may have their browsers already set at a large text display for readability - you have no control over that....
The good news is that this is the only page I see on your site that is built this way - all other pages are table-based, and while that approach is also uber-retro, at least it doesn't suffer from this potential overlapping problem.
