Hi Cindy,

It feels to me, just on what you've written, that you might be trying  
to do too much with a single table. How would you attack the design  
if you had the freedom to come up with completely different solutions  
for each goal of your users? If you could have 'n' designs instead of  
1, what would each of the 'n' designs look like?

By answering that question, you might see a way to produce the  
designs you need with 1 or 2 elements, the table being one of them.

Just a thought,

Jared
