this is the code:

combo.removeAllItems();
                combo.addItem("PCS");
                combo.addPopupMenuListener(new javax.swing.event.PopupMenuListener() {
                    public void popupMenuCanceled(javax.swing.event.PopupMenuEvent evt) {
                    }
                    public void popupMenuWillBecomeInvisible(javax.swing.event.PopupMenuEvent evt) {
                    }
                    public void popupMenuWillBecomeVisible(javax.swing.event.PopupMenuEvent evt) {
                        comboPopupMenuWillBecomeVisible(evt);
                    }
                });
                
                combo.addMouseListener(new java.awt.event.MouseAdapter() {
                    public void mousePressed(java.awt.event.MouseEvent evt) {
                        comboMousePressed(evt);
                    }
                });
 
                TableCellEditor editor = new DefaultCellEditor(combo);
        
                TableColumnModel columnModel=Table.getColumnModel();
                TableColumn satuanColumn = columnModel.getColumn(2);        
                satuanColumn.setCellEditor(editor);

    public void comboPopupMenuWillBecomeVisible(javax.swing.event.PopupMenuEvent evt) {
         int[] selected = Table.getSelectedRows();
        
        if (selected.length>=1)
        {
             String cmd="select satuan1, satuan2, satuan3 from mbarang where idbarang="+model.getValueAt(selected[0], -1);
            ResultSetAdapter rsa=new ResultSetAdapter(con);
            if (rsa.executeQuery(cmd))
            {
                FilteredRowSet frs=rsa.getRowSet();
                if (frs.size()>0) {
                    try {
                        frs.first();                
                        combo.removeAllItems();
                        String s=frs.getString(1);
                        combo.addItem(s);
                        s=frs.getString(2);
                        if (!frs.equals("")) combo.addItem(s);                        
                        s=frs.getString(3);
                        if (!frs.equals("")) combo.addItem(s);
                    }catch (SQLException e) {
                    }
                }
            }
