I'm confused by what you mean "@ the background of a table." Do you mean the image is actually set as a table background?

You could create a DIV, give it a height and width then absolute position it.

use of this CSSes for second layer which is over.

for IE:

.selector {
filter: alpha(opacity=50);
}

for FF:

.selector {
-moz-opacity: .5;
}

if you want to comaptible for any browser use:

.selector {
	filter: alpha(opacity=50);
	filter: progid:DXImageTransform.Microsoft.Alpha(opacity=50);
	-moz-opacity: .5;
	-khtml-opacity: .5;
	opacity: .5; /* for future compatibility */
}

0.5 and 50 are present rate of transparent.

If you're trying to prevent theft of the background image, this won't do it. It'll stop viewers with little to no knowledge.
