How to disable the button in JTable

[Naveen Kumar]

Hi All,

I have JPanel.
In my JPanel I have one JTable and One JButton.(Button Name is Continue)

I wish to have a table rows such a way that, first column should have
button (in all rows..) and rest are all string columns (in all rows.)

If I click the continue Button on the JPanel I want to disable all the buttons in the JTable.
Any body please help me.

Regards
Naveen
