I've seen this question asked before, but never adequately answered.  Is it 
possible to render a JTable _row_ differently than other rows?  

For instance, say I have a single column table of numbers.  If the number is 
negative, I want the background color to be red.  If zero or positive, I want 
the background to be white.  Is this possible?

The Java Tutorial states that "...each column has a single cell renderer that 
draws all of its cells" and "you can specify different cell editors and 
renderers either by column or by data type."  This suggests to me that I can 
render _columns_ differently, but not rows.  Seems to me this is a real 
weakness with JTable.
