I am developing a website but have come across this problem. There is a missing line after the first row of the layout table and it appears that it has moved to the bottom of the table. I have validated my website through W3C and it is as clean as can be. I have loaded the page in all major browsers except Internet Explorer (Mozilla Firefox, Safari, Google Chrome, and Opera) and Mozilla Firefox is the only one that does it. I use OS X 10.6.4. I have had somebody else using OS X try it as well and it didn't work. I even tried clearing my cache. Is it something wrong with Mozilla Firefox or with my website?

It is not a missing line, but caused by the height being calculated as 21px instead of 20px.
You can try to leave out the   in the TD elements to avoid that extra pixel.

Thanks. Removing the non-breaking spaces fixed it. :)
