Transparent table backgrounds?

[Chandler_90]

Just curious.
I'm trying to create an partially transparent image as a background for a table cell, which when rolled over will change to a readable format.

However, I have found that even though I can get the partially transparent gif I created to work it doesn't actually work due to the background of the table cell being constantly white.

Is there any method I can use to make the table cell or even the entire tables background transparent?

Thanks.

I appear to have sorted it.. I used a little css code as follows -

.FI2 {
font-size: 10px;
font-family:Verdana, Arial, Helvetica, sans-serif;
font-size: 10px;
text-align:center;
color:#000000;
background-color:#FFFFFF;
filter:alpha(opacity=50);
opacity: 0.5;

}

It seems to have worked.. I just need to slice things up a little
