mouseover rows with fixed columns

I want to be able to highlight rows that are moused-over in a grid with fixed columns. I found the following in the forums:

/javascript.forum.2266.4/mouseover-highlighting-first-column.html

but it doesn't seem to apply to version 2.0.

In version 2.0, how would I highlight an entire row that has fixed columns when it is moused over?

Thanks!
