Thanks for the response.

I will have to investigate spanning cells.  Wonder if the span stays 
with a visible row, or moves with the data when scrolling?  And if it 
would slow down things significantly, after I've just sped them up with 
the TableView?

In that case, I have constrained myself to 1% of all table view usages: 
I have always found this behavior extremely useful in spreadsheets and 
database views.  I wonder if your 99% number has statistics behind it, 
or is only an estimate based on your experience?
