You can use addRow( ... ) method -
DefaultTableModel model;
JTable table;
JScrollPane sc1;
model = new DefaultTableModel();
table = new JTable(model);
model.addColumn("RollNo");
model.addColumn("Name");
model.addRow(new Object[]{"",""});
table.addKeyListener(new KeyListener() {
public void keyPressed(KeyEvent e) {
if (e.getKeyCode()==KeyEvent.VK_ENTER) {
model.addRow(new Object[]{"", ""}); } }
public void keyReleased(KeyEvent e) { }
public void keyTyped(KeyEvent e) { } } );
sc1 = new JScrollPane(table,JScrollPane.VERTICAL_SCROLLBAR_ALWAYS, JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
But you should implement it in your own way.
