Table event listener for both columns and rows

Question

My table listener only gives me the printed values when I click on different rows and not when I click on different columns. Do I need 2 listeners (one inside the other one) to get a change recorded each time I click on a cell in the table? Here is the listener code:
      ListSelectionModel rowSM1 = jTable1.getSelectionModel();
      rowSM1.addListSelectionListener(new ListSelectionListener() {
        public void valueChanged(ListSelectionEvent e) {
          System.out.println("I am here");
          ListSelectionModel lsm = (ListSelectionModel)e.getSource();
          if (e.getValueIsAdjusting()) {
            return;
          if (lsm.isSelectionEmpty()) {
            //no rows are selected
          else {
            selectedSiteRow = new Integer(lsm.getMinSelectionIndex() + 1).toString();
            System.out.println("selectedSiteRow = " + selectedSiteRow);
            SetupNum = selectedSiteRow; // row that the user selected
            ObjectNum = "1";
            objnum = "1";
            dataModels.remove("O"); // remove the object tables from the dataModels hashtable
            dataModels.remove("P"); // remove the object tables from the dataModels hashtable
            for (int i = 0; i < wholefile.size(); i++) {
              setupnum = selectedSiteRow;
              if (wholefile.elementAt(i).toString().charAt(0) == 'O') {
                processLine(wholefile.elementAt(i).toString(), columnNamesO);
                String keyO = "O";
                DefaultTableModel modelO = (DefaultTableModel)dataModels.get(keyO);
                jTable2.setModel(modelO); // change the table to the new table model
              if (wholefile.elementAt(i).toString().charAt(0) == 'P') {
                processLine(wholefile.elementAt(i).toString(), columnNamesP);
                String keyP = "P";
                DefaultTableModel modelP = (DefaultTableModel)dataModels.get(keyP);
                jTable3.setModel(modelP); // change the table to the new table model
    );The words "I am here" only appear when I click on rows and not when I click on columns of that same row. Anyone know why?
Also, each time I click on a row, "I am here" appears 2 times. I know I read that someone else had that problem. I will try to find the solution to that one in the forum.
Thanks.

Answer 1

I found out how to get the column, but I can't seem to get them together. Here is the listener for the column:
      ListSelectionModel colSM1 = jTable1.getColumnModel().getSelectionModel();
      colSM1.addListSelectionListener(new ListSelectionListener() {
        public void valueChanged(ListSelectionEvent e) {
          if (e.getValueIsAdjusting()) {
            return;
          ListSelectionModel lsm = (ListSelectionModel)e.getSource();
          if (lsm.isSelectionEmpty()) {
            //no columns are selected
          else {
            SelectedC = lsm.getMinSelectionIndex();
      });These are 2 different listeners and I really want to find out what row,column has changed. Is there any way to combine these somehow? Thanks.
