public class JvDefaultTableCellRenderer
extends JLabel
implements TableCellRenderer

Custom cell renderer that honors the table's "enabled" property and makes non-editable cells the same color as the background. Also uses its own font rather than the table's font so that each cell may be given its own font. Note: I had way too many problems extending DefaultTableCellRenderer. Some of the display optimizations there make changing the background of a particular cell difficult, if not impossible. Occasionally cut and paste is the best code reuse technique.
