I am validating a particular column of JTable. My requirement is that all the cells of that column should allow only alphabets.I have added keylistener to object of Jtable and written some logic as follows:

```
public void keyTyped ( KeyEvent e ) {

    if(!(e.getKeyChar()>='a' &&e.getKeyChar()>='z')) {
        getToolkit.beep();
    } 
}

```

Initially when focus is on cell and type something the key event is triggered fine, but when I click on the same cell and type, the key event is not getting trigerred. So I decided to disable the mouse click event on JTable. How can I disable the mouse click event on cells of JTable?
