The actual table size doesn't change when you maximize the window. I'm guessing it's just a visual thing?
If you are using Internet Explorer 7 you could try the following, but I don't know how it affects other colours or websites (you can reverse when finished). Please note that I haven't tested this.
1. Open IE7
2. Go to Tools > Internet Options
3. Click on "Colors"
4. Remove the check from "Use Windows Colors"
5. Change the background colour to black (you might want to change the text colour to something different just in case it hides something with black on black)
6. Click OK
7. Click on "Accessibility"
8. Check "Ignore colors..."
9. Click OK twice.
Only OP can answer if FOD intends to change the background colour.
