Those two are all you need to change if everything is guaranteed to be 
static.  But if the data can change, the job gets more complicated.  

First you have to handle mapping of filtered row numbers to unfiltered 
row numbers in the the setValueAt() and isCellEditable() methods.

But you also need to listen for changes in the underlying table model, 
map the unfiltered row numbers to filtered row numbers, and fire table 
model events with the filtered row numbers.  Of course you will have to 
ignore events that only describe changes to filtered rows.

Another issue to consider is that a change in the underlying table model 
may change the filtering criteria.  So an UPDATE event could turn into a 
DELETE event, an INSERT event, or a combination of all three.
