Re: Traversing through DOM, identifying td's and manipulating

Seconding Joris's recommendation -

One of the keys to good DOM scripting is to defer to the compiled code 
of the browser whenever possible. Safari, Firefox, etc may have faster 
and faster scripting engines every day, but no JS loop will ever beat 
the compiled, native code of the browser itself for the same task. 
Performance may not matter when considering a tree with 2 or 3 branches, 
but if a client ends up with a dataset of 7000 rows, you'll hope you 
wrote your code efficiently.

In this case the browser can do this traversal for you via CSS, or you 
can loop with JS. The CSS route leverages the browser's compiled code, 
so it's the best choice. The approach has an added benefit of reducing 
the amount of code you'll be writing.
