Status: RESOLVED DUPLICATE of bug 195261

(Core :: Layout: Tables, defect)

Table cells have background images. I want to change them in onMouseOver 
event, but it doesn't work. In the above page, the red light in menu buttons 
on the left should light up when mouse passes over them, but it doesn't (at 
least not in Mozilla - it works fine in IE 6.0).

When I check cell.background (before changing it), it's 'undefined'. After 
changing it, it has the appropriate value, but the image itself stays unchaged.

Reproducible: Always

"background" is not a valid attribute of <td>; it appears that we map the
attribute to CSS, but we don't reflect it in the DOM, so trying to change
this.background on a <td> has no effect.
