     initComponents();
     
    //DefaultTableModel dm = new DefaultTableModel();
     
    //dm.setDataVector(new Object[][]{{"button 1", "foo"}, {"button 2", "bar"}}, new Object[]{"Button", "String"});
     
     jTable1.getColumn("Button").setCellRenderer(new ButtonRenderer());
     
     jTable1.getColumn("Button").setCellEditor(new ButtonEditor(new JCheckBox()));
     
    ((DefaultTableModel)jTable1.getModel()).addRow(new Object[] {"NX1001","Product name","Delete"});

    outPut :



    1. but I don't want the empty records ! I only need the last record which I added ?


    2. I assume tht the below function is the one which triggers or acts as a event ! how to get the row[0] value when the delete button is clicked
      public ButtonEditor(JCheckBox checkBox) {
        super(checkBox);
        button = new JButton();
        button.setOpaque(true);
        button.addActionListener(new ActionListener() {
          public void actionPerformed(ActionEvent e) {
            fireEditingStopped();
          }
        });
      }

    the below function is the one which triggers or acts as a event
    Sort of. The actionPerformed() method is called when there is an Action Event on the button its a listener for.

    Are the errors, logic errors or what kind of error are they? Compile or runtime exceptions?
