How can I add JCheckBox to each row?

[batya]

my code :
public class JTableTTest {

public static void main(String[] argv) {

//data is a list of ambulances
ArrayList<Ambulance> data=new ArrayList<Ambulance>();
Ambulance A2 = new Ambulance(13, "צפון",false,"לבן");
Ambulance A3 = new Ambulance(11, "מרכז",false,"לבן");
Ambulance A4 = new Ambulance(10, "דרום",false,"לבן");
Ambulance A5 = new Ambulance(20, "מרכז",false,"לבן");
data.add( A2);
data.add(A3);
data.add(A4);

Vector rowData = new Vector();
for(Ambulance a:data)
{

Vector ambulance=new Vector
(Arrays.asList (a.getAmbulanceNumber(),a.getIsInJob(),a.getKindOf Ambulance());
rowData.add(ambulance);
}

String[] columnNames = {"a","b","c","d"};

Vector columnNamesV = new Vector(Arrays.asList(columnNames));

JTable table = new JTable(rowData, columnNamesV);
JFrame f = new JFrame();
f.setSize(300, 300);
f.add(new JScrollPane(table));
f.setVisible(true);
}

Please read the Sun tutorial on JTable, and you'll learn how to add check boxes to a jtable column. If this is not what you want to do, you may wish to ask a more detailed question.
