JTable: moving from cell to cell in a row

Question

Hello,
in the following code the first cell is editable when the programme comes up.
To move to the next cell (no matter whether you entered some characters or
not), you have hit either <Enter>, <Tab> or <Right arrow> - but twice. To move
on to the third and fourth cell, only one hit is sufficient.
What actually happens becomes visible, when you change the code to make the 3rd
cell editable at programme start. Then you see that the first hit of <Enter>,
<Tab> or <Right arrow> goes back to the 1st cell. I would accept this for the
<Enter> key, but definitely not for <Tab> and <Right arrow>.
Any idea how this behaviour could be avoided?

public class ReadyForInput extends JFrame {
  public ReadyForInput() {
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setSize(300, 100);
    setLocationRelativeTo(null);
    setTitle("ReadyForInput");
    Container cp = getContentPane();
    String headers[] = {"Key", "Value", "Description", "Comment"};
    JTable table = new JTable(1, headers.length);
    DefaultTableModel dtm= (DefaultTableModel)table.getModel();
    dtm.setColumnIdentifiers(headers);
    JScrollPane scrollPane = new JScrollPane(table);
    cp.add(scrollPane, BorderLayout.CENTER);
    table.getSelectionModel().setSelectionInterval(0,0);
    setVisible(true);
    table.editCellAt(0, 0);
//    table.editCellAt(0, 2); // 3rd cell editable
  public static void main(String args[]) {
    java.awt.EventQueue.invokeLater(new Runnable() {
      public void run() {
     new ReadyForInput();
}

Answer 1

table.changeSelection(0, 2, false, false);
table.editCellAt(0, 2); // 3rd cell editable
