1. Create a table with "text-decoration: underline"
2. Create a TD in the table with "text-decoration: none"

Actual Results:  
The TD had an underline.

Expected Results:  
It should have repressed the underline.

Possibly invalid (e.g. see Bug 10458) but moving to somewhere more appropriate
since I'm not certain.

Well, something certainly seems strange since (font-weight: normal) overrides
(font-weight: bold) but (text-decoration: none) does not override
(text-decoration: underline).

Yeah, this is not a bug.
See http://www.w3.org/TR/CSS21/text.html#lining-striking-props
> Text decorations on inline boxes are drawn across the entire element, going
across any descendant elements without paying any attention to their presence.

The line is not TD's. Because text-decorations is not inherited. The owner of
the line is parent table element.
