IsCellEditable() to disable cell editing for specific columns

Question

Hello experts:
My SSCCE for this question is at the below link:
http://forum.java.sun.com/thread.jspa?threadID=5293914&messageID=10244030#10244030
My question is how do I disable cell editing for all but the "Price" column of my table in the SSCCE. I tried adding the below lines of code right after creating the JTable. But get compilation errors.
//Here is the block of code that I am trying to include.
     @Override                                                       
     public boolean isCellEditable(int row, int col) {     
     if (col == 7) {                                                  
               return true;
          } else {
               return false;
     } //Below is the method in detail03.java showing the block of code added
private JScrollPane BuildEmptyTable() {
     model = new DefaultTableModel();
     model.addTableModelListener( this );
     model.setColumnIdentifiers(new String[] { "SKU","Qty", "Price"});
        tblDetailTest = new JTable(model);
     @Override                                                       
     public boolean isCellEditable(int row, int col) {     //     <----- I tried placing the
     if (col == 7) {                                        //                  the code block here
               return true;
          } else {
               return false;
     tblDetailTest.setRowHeight(20);
     tblDetailTest.setPreferredScrollableViewportSize(new Dimension(900, 100));
     JTableHeader tblHdr = tblDetailTest.getTableHeader();
     tblHdr.setBackground(Color.yellow);
     JScrollPane scrollPane = new JScrollPane(tblDetailTest);
     return scrollPane;
}Can somebody please guide me? Thank you very much.

oops!
Sorry, my bad! I did not tell you what I tried. Following your suggestion, I made the following 2 changes to the code:
In the method, BuildEmptyTable(), where I build the table structure, I have the following statement:
     tblDetail = new JTable(model){
public boolean isCellEditable(int row, int col) {
       return col == 8;
};And in a separate method after the table is populated with data, I have the below code:
     tblDetail.getModel().addTableModelListener(new TableModelListener() {
     public void tableChanged(TableModelEvent e) {
     if (e.getType() == TableModelEvent.UPDATE)
          int row = e.getFirstRow();
          int column = e.getColumn();
             if (column == 8){
               //code here
               System.out.println("Updating item price!");
     }I do understand that the message gets displayed as many number of times equal to number of rows inserted into the table, because of the UPDATE event. But my problem is I do not know how to make a code change to do what I exactly want, as I have indicated in my previous note. Meaning I want the listener to be called only when the
data in the editable cell changes.
Thank You.
