making JTable rows not editable

i need to make a jtables rows and columns to not be editable, but i also need it to be able to be selectable. i know one way to do it is to extend defaulttablemodel and overwrite the iscelleditable method, but the problem is that i'm already extending jframe. is there any other way to do this keeping jframe extended, because i need it to be extended?

thanks for the help
