JTable编辑器中的键绑定

我找到了键绑定主题( JTable Key Bindings )与此类似。我了解到它的键绑定绑定到表,而不是编辑器。

我的目标是在编辑器上以VK-ENTER结尾的任何输入,它执行动作pindah(即添加新行并设置光标在新行上闪烁)。很抱歉,我没有从那个例子中学习。

有办法吗?

这是我的代码(不包括导入,因为Eclipse会自动建议):

public class Fpos extends JFrame 
{
public static void main(String[] args) 
{
    EventQueue.invokeLater(new Runnable() 
    {
        public void run() 
        {
            try 
            {
                Fpos frame = new Fpos();
                frame.setVisible(true);
                frame.setLocationRelativeTo(null);  //make frame center of screen                   
            } catch (Exception e) {e.printStackTrace();}
        }
    });
}

public Fpos() 
{
    //create Jpanel
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setBounds(10, 10, 1300, 700);
    JPanel contentPane = new JPanel();
    contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
    setContentPane(contentPane);
    contentPane.setLayout(null);
    //create label TOTAL
    JLabel lblTotal = new JLabel("TOTAL : Rp.");                
    lblTotal.setFont(new Font("Wide Latin", Font.PLAIN, 30));
    lblTotal.setBounds(33, 25, 312, 31);
    contentPane.add(lblTotal);
    //create label Total Amount
    JLabel lblNewLabel = new JLabel("123,456,789");
    lblNewLabel.setHorizontalAlignment(SwingConstants.RIGHT);
    lblNewLabel.setFont(new Font("Wide Latin", Font.PLAIN, 60));
    lblNewLabel.setBounds(583, 19, 659, 61);
    contentPane.add(lblNewLabel);
    //create jtable in scrollpane
    String[] columnNames = {"PLU", "NAME", "UOM", "QTY", "PRICE","AMOUNT"};
        Object[][] data = {{"", "", "", "", "", ""}};
         DefaultTableModel model = new DefaultTableModel(data, columnNames);
     JTable table = new JTable(model);                  
     table.setFont(new Font("Tahoma", Font.PLAIN, 20));
     table.setRowHeight(25);
     JScrollPane sp=new JScrollPane(table);             
     sp.setBounds(25,100,1240,556);
     contentPane.add(sp);
     //set column width
     TableColumnModel columnModel = table.getColumnModel();
     short a[] = {150,540,50,150,150,200};
     for(byte i=0;i<6;i++) { columnModel.getColumn(i).setPreferredWidth(a[i]); }
     //render column format left alignment
     for(byte i=0;i<3;i++) {table.getColumnModel().getColumn(i).setCellRenderer(new TextTableCellRenderer());}
     //render column format ###,##0 right alignment
     for(byte i=3;i<6;i++) {table.getColumnModel().getColumn(i).setCellRenderer(new NumberTableCellRenderer());}
     //make cursor blinking on selected cell + select all cell value
    SwingUtilities.invokeLater(new Runnable()
    {

        {
             table.changeSelection(0, 0, false, false);

                editor.setFont(new Font("Tahoma", Font.PLAIN, 20));
                editor.requestFocusInWindow();
                ((JTextComponent)editor).selectAll(); //select all cell value                   

                //key binding
                Action pindah = new AbstractAction()

                        //i want to add new blank row but somehow there is value on column 0, so I have to set it blank. If you have a solution on this, you're very welcome
