class RadioButtonRenderer implements TableCellRenderer {

            return null;
        return (Component) value;
    }
}

class RadioButtonEditor extends DefaultCellEditor implements ItemListener {
    private JRadioButton button;

    public RadioButtonEditor(JCheckBox checkBox) {
        super(checkBox);
    }

    public Component getTableCellEditorComponent(JTable table, Object value,
            boolean isSelected, int row, int column) {
        if (value == null)
            return null;
        button = (JRadioButton) value;
        button.addItemListener(this);
        return (Component) value;
    }

    public …
