How can change the focus on the JTable?

I have built simple java swing application. Now in my JPanel, I have some JTextField and one JTable. So I have implemented a my custom focus, if the focus is on the JTextFiled1 and I press ENTER, the focus automatically change on the JTextFiled2 etc. The last element that receive the focus is JTable. Now I don't want that the focus is on the first column but on the fourth column, so I have this code:

textDescrizione.getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_ENTER,0), "myTabAction");
textDescrizione.getActionMap().put("myTabAction", new AbstractAction("myTabAction") {
    public void actionPerformed(ActionEvent e) {
        tableConti.requestFocus();
        tableConti.editCellAt(0,4);
    }
});

this code works, I have the focus on my fouth cell, but if I try to press right button on my keyboard, the focus is not of the five column but on the first column. How can I change this?

Another question is, I have implemented a keyListener on my JTable, so if I try to press F5 when JTable have the focus, I call a method. Also thi works but the focus remains on the cell.

This is the code:

keyListener

public class MyKeyListenerSalvataggio extends KeyAdapter{
    public void keyReleased(KeyEvent e) {
        if(e.getKeyCode() == KeyEvent.VK_F5){
            salva();
        }

    }
};

tableConti.addKeyListener(new MyKeyListenerSalvataggio());

After that I have press F5, the method salva() finish this is the situation:

enter image description here

As you can see, I'm not able to clean the value of the table, and delete the focus on the cell.

You need to tell the table to stop editing the cell. See Table Stop Editing for a couple of approaches:

  1. In the ActionListener you stop the cell editing, or
  2. You can set a property of the table to stop editing when it loses focus
