how to make the JTable.editCellAt(row,col) work

hi,all

I'd to start editing the cell at row and column programmatically,
the methond I used was JTable.editCellAt(row,col),
it's prepered for this,I think,
but there is something wrong,
the whole code as follows:

public class FrameTest {

    Logger logger = Logger.getLogger(FrameTest.class.getName());
    static int width = 500;
    static int height = 300;
    JFrame frame;
    public FrameTest(){
        logger.setLevel(Level.ALL);

        createUI();
    }

    JTable table;
    public void createUI(){
        logger.fine("start createUI");

        frame = new JFrame("TestFrame");
        frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
        frame.setPreferredSize(new Dimension(width,height));

        initTable();

        frame.add(new JScrollPane(table));
        frame.pack();
        frame.setVisible(true);
    }

    DefaultTableModel tableModel;
    static final String[] columnNames = {"a","b","c","d","e","f","g","h"};
    private void initTable(){
                logger.fine("start initTable");
        tableModel = new DefaultTableModel(columnNames,2);
        table = new JTable(tableModel);
        table.setRowSelectionAllowed(false);

        table.requestFocusInWindow();
        boolean isEditing = table.editCellAt(0, 1);
        looger.info("is in editing?:"+isEditing);
    }

    public static void main(String[] args){
        new FrameTest();
    }
}

it can't work yet in my PC,
the envionment is Eclipse3.2 /3.1.2 and JDK1.5/1.6,
is there any wrong?

best regards,
Richard
