quiero unJTable que consta de 2 columnas (teniendoRadioButton) Activo e inactivo, de modo que si la columna activa esSelected entonces RadioButton inactivo obtieneUnselected y Viceversa significa que en una sola fila solo se puede seleccionar 1 botón de radio de entre 2 botones de radio. El código para el botón de radio está abajo. No puedo 2 agregar grupo de butt para estas 2 columnas.

 public class NewJFrame extends javax.swing.JFrame {
    DefaultTableModel dt;
    public JRadioButton radioButton=new JRadioButton();


       public class RadioButtonCellEditorRenderer extends AbstractCellEditor implements TableCellRenderer, TableCellEditor, ActionListener {



            public RadioButtonCellEditorRenderer() {

                radioButton.addActionListener(this);
                radioButton.setOpaque(false);
            }

            @Override
            public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
                radioButton.setSelected(Boolean.TRUE.equals(value));
                return radioButton;
            }

            @Override

                return radioButton.isSelected();
            }

        }
