They don't support the "background" attribute. The content model does, but the table rows themselves don't render the image. In nav4 what happens is that if the TR has a background then the cells inherit it. If the cell specifies a background then it overrides the TR background. Same inheritance applies to TABLE too.

I'm stealing this bug. There's a real question if we want to mimic this Nav bug (yes it's a bug, not a feature). IE does NOT propogate backgrounds into table cells. If we do support this, it should be a quirk only. The best way to support this is with a custom HTML style rule for the table cells that propogates BGCOLOR and BACKGROUND attributes from the table and tr into the cell. CSS should always apply where it is mapped to (ie: not inherit into cells).

Using 8/16 Apprunner, I will verify this bug fixed. Assigning 'bgcolor' or 'background-color' to TABLE and/or TR propogates color to the cells. The one glitch is that there is color showing on border which should be ignored - this is an open problem that is already written up in bug #8524
