Populating an existing vector from ResultSet

Question

I want to populate a JTable's Table Model's Vector with data from a ResultSet. The code that I have
seen follows the general pattern of the code below, from "The JDBC:�Practical Guide for Java Programmers"
It creates a new Vector and fills the data in.
         public void presentResultSet(ResultSet rs)
     throws SQLException {
     Vector dataVector = new Vector();     //     ----------------------------- create an NEW Vector
     if (!rs.next())
         JOptionPane.showMessageDialog(null,"No records for customer");
     else {
         do {
          Vector rowVector = new Vector();
          rowVector.addElement(rs.getString("Title"));
          rowVector.addElement(rs.getString("Type"));
          dataVector.addElement(rowVector);
          } while (rs.next());
     Vector headVector = new Vector(2);
     headVector.addElement("Title");
     headVector.addElement("Type");
     dataTable = new JTable(dataVector, headVector);
     dataTableScrollPane.setViewportView(dataTable);
     I want to populate an existing vector which already exists, and has several methods attached to it.
Please look at the code below, and tell me if it is on the right track, or what changes need to be made.
     //     ------------------------------------------------- To populate an existing (tableModel) vector:
     int rows = 10;
     int cols = 10;
     Table2Model t2Model = new Table2Model();
     while (rs.next()) {
          for ( int r = 0; r < rows; r++ ) {                         
               for ( int c = 0; c < cols; c++ ) { // visibleColumns                    
                    ( ( Vector )t2Model.elementAt( r ) ).setElementAt( rs.getString( c+1 ), c );
     Many thanks in advance
