Something like this? http://grouper.ieee.org/groups/detailed_index_s.html

The code maybe a bit more complicated that what you want because the state is 
saved in a cookie (the tree is small enough that the cookie remains within the 
4K maximum size).

It uses nested tables and in order not to screw up the table uses colspans (as 
far as I remember, I wrote this a while back).

Feel free to reuse if you want.
