My tables are causing problems in IE8. I cannot get the dividing borders in the table header to appear above the gradient (except for in one spot, which you can see in the image below). The borders appear fine in every other browser and even in IE8 Compatibility Mode. Any ideas on how to fix this? Here is a test site for everyone to see the applied code.

Here is the table header’s CSS, but you can view the entire CSS file here:

I found a fix, but I’m not very happy with it since it isn’t valid HTML anymore…but this seems to fix the problem in older versions of IE:
I showed this to my boss, he did not approve, so I am still looking for a solution!!!
