Today, I have an answer for this. Observe this clip which I found at http://www.chka.de/swing/table/faq.html : > Why doesn't the JTable appear "greyed-out" when it is set to disabled? > > The default renderers don't react to the JTable's enabled state.

Now the table header looks disabled when it has been. :-) Jim. ---------------------------------------------------------------------- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
