There is a way to format a table so the content appears first:
| & nbsp; | main content here |
| menu items |
The non breaking space (& nbsp) causes the “main content” here to display first before the menu items. Copy and paste into a test page then view source, left a border there so you can see how it works.
I wouldn’t pop all your page content in it though as having it all in one huge table will slow loading considerably, just your meaty stuff!
