Tables - The Definitive Guide to Java Swing - page 678

■ Note Keep in mind that one renderer component is used for every cell of every column of a particular

class. No individual renderer is created for each cell.

The sample program that used the EvenOddRenderer to generate Figure 18-7 is shown in
Listing 18-3.
