How can I add KeyListener to JTable editor

Question

Hi, I want to know how can I add a KeyListener to a JTable editor?
I want to capture the event when any of the cell in the jtable has a key typed.

If your goal is to check the entered value, it's more elegant to do this in overriding
DefaultCellEditor#stopCellEditing and return false when the value is not correct.
Example from a DateEditor:
        @Override public boolean stopCellEditing() {
            String value = ((JTextField)getComponent()).getText();
            if(!value.equals("")) {
                try {
                    formatterE.parse(value);
                } catch (ParseException e) {
                    ((JComponent)getComponent()).setBorder(new LineBorder(Color.red));
                    return false;
            return super.stopCellEditing();
        }
