I'm using the Nimbus L&F with a JTable that has a boolean (checkbox) element as one of its columns.
The issue I'm having is that the boolean column does not follow the natural row background alternations present in the Nimbus L&F.
JTable - Boolean Cell Type - Background
It's a bug in the synth-installed renderer, quick hack is to force the rendering checkbox opacity to true:
((JComponent) table.getDefaultRenderer(Boolean.class)).setOpaque(true);
hmmm and I have opposite problem, check that, really nobody can hepl you without code example, maybe someone can play with unselected AlternateTableColor with usage of TableCellRenderer

I know it is old post, but for other searchers: I used jxtable() and that solved this problem :)
