Yes. It's simple. I've done it - many times. You just need timing loops
and possibly specific-location iding.
The idea is roughly this: delay the execution of the mouseout code a bit
and cancel it completely if a new mouseover event occurs _in the same row_.
Depending on what you are actually trying to do with the mouseovers, you
may be able to cancel the -out code on _any_ -over. Each situation is
slightly different but the main method is the same.
Generally, I'd use events on the cells only, not the rows. It might be a
bit more hassle but I think it works better in the long run.
