Adding JComboBox to a JTable cell [duplicate]

How to add a JComboBox to a JTable cell?

I'm finding it difficult to add JComboBox to one of the cells of a JTable, I tried the code below but it's not working..

How can I add jcombobox to a particular cell?

On pressing enter a new jcombobox should be added automatically to the desired column.

jTable1 = new javax.swing.JTable();
mod=new DefaultTableModel();
mod.addColumn("No");
mod.addColumn("Item ID");
mod.addColumn("Units");
mod.addColumn("Amount");
mod.addColumn("UOM");
mod.addColumn("Delivery Date");
mod.addColumn("Total Amount");
mod.addColumn("Notes");
mod.addColumn("Received");
mod.addRow(new Object [][] {
        {1, null, null, null, null, null, null, null, null}
    });
jTable1.setModel(mod);
jTable1.getColumnModel().getColumn(1).setCellEditor(new DefaultCellEditor(generateBox()));
jTable1.setColumnSelectionAllowed(true);


Code to generate ComboBox

private JComboBox generateBox()
 {
     JComboBox bx=null;
     Connection con=CPool.getConnection();
     try
     {
         Statement st=con.createStatement();
         String query="select distinct inid from inventory where company_code="+"'"+ims.MainWindow.cc+"'";
         ResultSet rs=st.executeQuery(query);
         bx=new JComboBox();
         while(rs.next()){
             bx.addItem(rs.getString(1));
         }
         CPool.closeConnection(con);
         CPool.closeStatement(st);
         CPool.closeResultSet(rs);
     }catch(Exception x)
     {
         System.out.println(x.getMessage());
     }
             return bx;

 }
