How do you change JTableHeader on the fly?

[Sam Zheng]

I have a JTable with one specific header. I want to change the header to another one in the program when a specific condition is satisfied. How can I do that?
Thanks!

table.getColumn( Object identifier ) or table.getColumnModel().getColumn( int index ) will get you a table column. Then use either setHeaderValue( Object value ) or setHeaderRenderer( TableCellRenderer renderer ) on the table column to make the appropriate changes. You may have to call invalidate(), validate(), or repaint() on the table to get the changes to show up...
