How to put JTextfield and JButton in a cell of JTable

Question

I'm trying to put two Components into one cell of a JTable. This is no
problem (in the TableCellRenderer) unless it comes to editing in these
cells. I have written my own CellEditor for the table.but there is one
minor problem: Neither the JTextfield nor the JButton has the focus so I
can't make any input! Does anybody know what's wrong, please help me for this issue ,plese urgent

public class TableEdit extends JFrame
     JTable table = new JTable();
     private String[] columnNames = {"non-edit1", "edit", "non-edit2"};
     public TableEdit()
          super("Table Edit");
          setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          createGUI();
          setLocationRelativeTo(null);
          setSize(400, 300);
          setVisible(true);
     private void createGUI()
          table.setModel(new DefaultTableModel(3,3)
               public int getColumnCount()
                    return 3;
               public boolean isCellEditable(int row, int column)
                    if(column == 1)
                         return true;
                    return false;
               public String getColumnName(int column)
                    return columnNames[column];
               public int getRowCount()
                    return 3;
               public Class getColumnClass(int column)
                    return String.class;
               public Object getValueAt(int row, int column)
                    return row + "" + column;
          table.setRowHeight(20);
          table.setDefaultEditor(String.class, new MyTableEditor());
          JScrollPane sp = new JScrollPane(table);
          add(sp);
     public class MyTableEditor extends AbstractCellEditor
     implements TableCellEditor
          JPanel jp = new JPanel(new BorderLayout(5,5));
          JTextField tf = new JTextField();
          JButton btn = new JButton("...");
          public MyTableEditor()
               jp.add(tf);
               jp.add(btn, BorderLayout.EAST);
               btn.addActionListener(new ActionListener(){
                    public void actionPerformed(ActionEvent e)
                         JOptionPane.showMessageDialog(null, "Clicked Lookup");
          public Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected, int row, int column)

               return jp;
          public Object getCellEditorValue()
               return tf.getText();
     public static void main(String[] parms)
          new TableEdit();
