JTable java

Salut,
Ajouter cette instruction :
model.addRow(New Object [] {"String ou klk chose"});
tel que model est le model de votre jtable
DefaultTableModel model = new DefaultTableModel(obj,vals);

voir ce code et consantrer bient

public class MyDefaultSecondTableModel extends AbstractTableModel {
private ArrayList colonneName = new ArrayList();
private ArrayList colonneLastName = new ArrayList();
...
public void addNewRow(int ligne) {
int addline = getRowCount();
if (ligne != -1)
addline = ligne +1;
colonneName.add(addline, "Name");
colonneLastName.add(addline, "First Name");
...
this.fireTableStructureChanged();
}
public void removeNewRow(int ligne) {
if (getRowCount() == 0 || ligne < 0)
return;
colonneName.remove(ligne);
colonneLastName.remove(ligne);
...
this.fireTableStructureChanged();
}
...
}

public class JTableDirectRenderer3 extends JFrame {
...
public JTableExemple() {
JButton myAddButton = new JButton("Ajouter");
myAddButton.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e) {
MyDefaultTableModel refModel = (MyDefaultTableModel)myTable.getModel();
refModel.addNewRow(myTable.getSelectedRow());
}
});
JButton myRemoveButton = new JButton("Supprimer");
myRemoveButton.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e) {
MyDefaultTableModel refModel = (MyDefaultTableModel)myTable.getModel();
refModel.removeNewRow(myTable.getSelectedRow());
