Retrieving JTable column number when clicked

Question

Hello, I'm new in this forum but not so new to java.....but I'm really worried about an issue with an application made using Swing.
Well , my problem is with JTables. It's about selecting a table cell in order to get the column index when selected. Ok I'm able to get the column index when the cells are simple cells, but the problem appears when the cell is a JComboBox....It's imposible to retrieve the column index. I was trying and trying but finally I couldn't see what the solution is......and I must get that problematic index....
Please, I really need and advice.
Thanks in advance for your help
Best Regards

Hello, I created a short example of my java class:
* NewClass.java
* Created on 26 de octubre de 2007, 0:03
* To change this template, choose Tools | Template Manager
* and open the template in the editor.
package pruebas;
import java.awt.Container;
import java.awt.Dimension;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import javax.swing.*;
public class TableDemoApplet extends JApplet {
JTable table;
public TableDemoApplet() {
createGUI(getContentPane());
public void createGUI(Container contentPane) {
Object[][] rowData = new String[][] { {"98-43", "AraAra! SL"},
{"81-31", "Aragones Transports SA"},
{"12-72", "Rocca SL"},
{"99-10", "Rodriguez e Hijos SA"},
{"00-65", "Rimbau Motors SL"} };
table = new JTable(rowData, new String[] {"Part No", "Provider"});
JComboBox companyComboBox = new JComboBox(new Object[] {"AraAra! SL", "Aragones Transports SA", "Rocca SL", "Rodriguez e Hijos SA", "Rimbau Motors SL"});
companyComboBox.setEditable(true);
//new S15WorkingBackspace(companyComboBox);
// setup the ComboBoxCellEditor, DefaultCellEditor won't work!
table.getColumnModel().getColumn(1).setCellEditor(new ComboBoxCellEditor(companyComboBox));
table.getSelectionModel().setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
table.setPreferredScrollableViewportSize(new Dimension(400, 100));
addListener();
JScrollPane scrollPane = new JScrollPane(table);
contentPane.setLayout(new java.awt.FlowLayout());
contentPane.add(scrollPane);
contentPane.add(new JTextField("HALLO!"));
public void addListener(){
/*table.addMouseListener(new MouseAdapter(){
public void mouseClicked(MouseEvent e){
int column = table.getSelectedColumn();
table.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e) {
// get most recently selected column index
int column = table.getSelectedColumn();
System.err.println("numero de columna: " + column);
public static void main(String[] args) {
javax.swing.SwingUtilities.invokeLater(new Runnable() {
public void run() {
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(3);
TableDemoApplet demo = new TableDemoApplet();
demo.createGUI(frame.getContentPane());
frame.pack(); frame.setVisible(true);
I'm showing there the wrong behavior of the JTable, I hope this help you to help me :)
Thanks a lot for your time!!
