Disable jTable so that user cant enter any value & is stopped to do so

Question

Hi
my program has 2 options for user: 1. To enter a list of values(for which im using table), 2. To use default values embedded in the program.
for these options i have used jRadioButtons n ButtonGroup.When user selects DefaultValues radiobutton program uses default values,but when it selects DefaultValues radiobutton i want to disable the Table such that the user cannot enter any value in the cell and it should be visible to the user too that the table has been disabled.
The user should only b able to enter values in table if he/she selects the first option's radiobutton.
note: im using DefaultTableModel, if somebody can tell me any way other than using isCellEditable(),it would be more appreciatable
thanks
