Few issues(iframe/tables mostly) with the website I am building

Hello, as most of you know(since I ask a lot), I am building a website for a project.
Today I uploaded it on a free hosting server to see how it works online so I can start debugging.

Browsers Tested:

  • Chrome 16
  • Firefox 9
  • Opera 11.60
  • IE 6 & IE 8

Issues:
- Chrome: None

  • Firefox:
  1. There is a black line(about 4px) on the part that the top row of the table separates with the row below it.
    On all other browsers that line is barely visible, it’s 1px(height).
  • IE 6 & IE 8:
    Same issues with opera above + this issue:
    I have a table with few rows. I have set the td rows height to 9px each, but in IE they appear a bit larger, like 15 px and I got no idea why. Also tried td height:100%, didn’t work.

Any suggestions are welcome, since I am trying to fix these issues before I keep on building the site! :beer2:
