[displaytag-user] Changing background colour of td based on +/- value

[Mike Moran]

Hi. I'm trying to find out whether it is possible using displaytag to 
change the background colour of a table td cell based on whether the 
content is positive or negative. The sort of thing I am thinking of can 
be seen at: http://www.houseofmoran.com/displaytag/ideal.html

On that page I am changing the class of the td. An alternative is to 
wrap a span around the value (which I think could be done using a 
ColumnDecorator, yes?) An example of this: 
http://www.houseofmoran.com/displaytag/ok.html

So, is it possible to do ideal.html using displaytag? If not, can 
anyone confirm that ok.html is possible? It would be very helpful if 
someone could suggest some css to make ok.html look like ideal.html, 
but that's an added extra :-)

Thanks,

--
Mike
