Method

voidinsertTableModelListener(TableModel model, TableModelListener l, int index)
Inserts the table model listener at the particular index in the listeners' chain. 
if (!(model instanceof AbstractTableModel)) {
    model.addTableModelListener(l);
    return;
TableModelListener[] listeners = ((AbstractTableModel) model).getTableModelListeners();
for (TableModelListener listener : listeners) {
    model.removeTableModelListener(listener);
for (int i = 0; i < listeners.length; i++) {
    TableModelListener listener = listeners[i];
    if (index == i) {
        model.addTableModelListener(l);
    model.addTableModelListener(listener);
if (index < 0 || index > listeners.length - 1) {
    model.addTableModelListener(l);
DefaultTableModelmakeDefaultTableModel(String[] titleA, final Class[] typesA, final boolean[] canEditA)
Make DefaultTableModel by overriding getColumnClass and isCellEditable of DefaultTableModel. 
return new DefaultTableModel(new Object[][] {}, titleA) {
    Class<?>[] types = typesA;
    boolean[] canEdit = canEditA;
    @Override
    public Class<?> getColumnClass(int columnIndex) {
        return types[columnIndex];

intmodelIndexToDisplayIndex(JTable table, int modelIndex)
model Index To Display Index 
if (modelIndex >= 0) {
    RowSorter<?> rowSorter = table.getRowSorter();
    return rowSorter != null ? rowSorter.convertRowIndexToView(modelIndex) : modelIndex;

voidsaveTModelToCSV(String fileName, JTable table)
Saves information from a table interface element to a file in CSV format. 
if (!fileName.endsWith(".csv"))
    fileName += ".csv";
BufferedWriter out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(fileName), ENCODING));
TableModel model = table.getModel();

...
voidsetDataVector(DefaultTableModel model, Vector dataVector)
Removes all existing rows in the table model and adds the rows found in the input data vector. 
if (model != null) {

        dataVector = new Vector();
    } else {
        dataVector = (Vector) dataVector.clone();
