Problem with button's color in the JTable

Hi,


I've some problem when display JButton in a cell.


I've created a class that extends from JPanel and within a panel, there is a

JTable. The CellRenderer and the CellEditor of the table are already included

and I've no problem when executing them alone. However when I add this panel

into another panel dynamically, the button changed to white color. Do anyone

knows why?


Thanks.
