How to Add and delete a row while using Abstract Table Model

Question

Hi,
I need to do the following functionalities in JTable.I've done tht but a small problem.
1. Adding a row (Using addRow() method from DefaultTableModel).
2. Deleting a row(Using setRowCount() method from Default Table Model).
3. Sorting the table based on the selection of column(Using TableSorter which is using AbstracTableModel).
As the sorting is mandatory i've to change my model to Abtract Table Model
The problem is this Abstract Table Model doesn't have any methods to Add a row or deleting a row (setRowCount()).If anybody has written any utility method for this using Abstract Table Model help me.

Answer 1

Using TableSorter which is using AbstracTableModel).If your talking about the TableSorter class from the Swing tutorial, then you create the TableSorter class by passing it a TableModel. There is no reason you can't use the DefaltTableModel.
I changed the code in TableSorterDemo as follows:
        String[] columnNames = {"First Name",
                                        "Last Name",
                                        "Sport",
                                        "# of Years",
                                        "Vegetarian"};
        Object[][] data = {
            {"Mary", "Campione",
             "Snowboarding", new BigDecimal(1), new Boolean(false)},
            {"Alison", "Huml",
             "Rowing", new BigDecimal(3), new Boolean(true)},
            {"Kathy", "Walrath",
             "Knitting", new BigDecimal(2), new Boolean(false)},
            {"Sharon", "Zakhour",
             "Speed reading", new BigDecimal(20), new Boolean(true)},
            {"Philip", "Milne",
             "Pool", new BigDecimal(10), new Boolean(false)}
          DefaultTableModel model = new DefaultTableModel(data, columnNames)
               public Class getColumnClass(int c)
                    return getValueAt(0, c).getClass();
        TableSorter sorter = new TableSorter(model);
//        TableSorter sorter = new TableSorter(new MyTableModel()); //ADDED THIS
