Question

I have a jTable and it\'s got a table model defined like this:

javax.swing.table.TableModel dataModel = 
     new javax.swing.table.DefaultTableModel(data, c         


        

Answer 1

    //To clear the Contents of Java JTable

    DefaultTableModel dm = (DefaultTableModel) JTable1.getModel();

    for (int i = 0; i < dm.getRowCount(); i++) {
        for (int j = 0; j < dm.getColumnCount(); j++) {
            dm.setValueAt("", i, j);
        }
    }
