JTable with TableCellEditor ???

Hello

I have a JTable and I created a table cell editor for that can use a
JTextField customized, this is working. Now I need that when I press
enter in cell selected the edit is open in JTable and not change the
row before change.

The situation looks like below
Enter on Selected Cell --> open the edit (enter value = US$ 1.00) -->
press enter again, close the edit and request focus in next cell to
make the process again.

/* AbstractTableModel - Brazilian Portuguese US$ = R$ */

public class TipoPagtoTableModel extends AbstractTableModel{
    private List<TipoPagto> listaTipoPagto;
    private String[] colunas = {"Id","Tipo Pagto.","Valor(R$)"};

    public TipoPagtoTableModel(){
        this.listaTipoPagto = new ArrayList<TipoPagto>();
    }

    public TipoPagtoTableModel(List<TipoPagto> lista){
        this();
        this.listaTipoPagto.addAll(lista);
    }

    @Override
    public int getRowCount() {
        return this.listaTipoPagto.size();
    }

    @Override
    public int getColumnCount() {
        return this.colunas.length;
    }

    public String getColumnName(int column){
        //nome da coluna
        if(colunas[column] == "Id"){
            return "Id";
        }else if(colunas[column] == "Tipo Pagto."){
            return "Tipo Pagto.";
        }else if(colunas[column] == "Valor(R$)"){
            return "Valor(R$)";
        }
        return new String();
    }

     public Class getColumnClass(int column){
         if(colunas[column] == "Id"){
             return Long.class;
         }else if(colunas[column] == "Tipo Pagto."){
            return String.class;
         }else if(colunas[column] == "Valor(R$)"){
            return BigDecimal.class;
         }
        return String.class;
    }

    @Override
    public Object getValueAt(int rowIndex, int columnIndex) {
        TipoPagto tp = this.listaTipoPagto.get(rowIndex);
        switch(columnIndex){
            case 0: return new
FormataCodigos().retornaCodigoFormatado(tp.getIdPagto());
            case 1: return tp.getTipo();
            case 2: return tp.getValor();
            default: return new String();
        }
    }

    public void setValueAt(Object aValue, int rowIndex, int
columnIndex) {
        listaTipoPagto.get(rowIndex).setValor(new
BigDecimal(aValue.toString()));
        fireTableRowsUpdated(rowIndex, columnIndex);
    }

    public boolean isCellEditable(int rowIndex, int columnIndex) {
        if(columnIndex == 2){
            return true;
        }else{
            return false;
        }
    }

    public Boolean deleteAll(){
        this.listaTipoPagto.clear();
        fireTableDataChanged();
        return true;
    }

    public boolean removeRow(int line){
         this.listaTipoPagto.remove(line);
         fireTableDataChanged();
         return true;
   }
}

/* TableCellEditor */
public class TipoPagtoTableCellEditor extends AbstractCellEditor
implements TableCellEditor {
    private JTextField txtField;

    public TipoPagtoTableCellEditor(){
        txtField = new JMoneyField(15);
        txtField.setFont(new Font("Tahoma", Font.BOLD, 12));
    }

    @Override
    public Object getCellEditorValue() {
        return new BigDecimal(txtField.getText().replaceAll("\\.",
"").replace(",", "."));
    }

    @Override
    public Component getTableCellEditorComponent(JTable table, Object
value, boolean isSelected, int row, int column) {
        txtField.setText((String)value);
        return txtField;
    }
}

/* JFrame */
List<TipoPagto> lista = new TipoPagtoDAO().getFormaPagto();
TipoPagtoTableModel model = new TipoPagtoTableModel(lista);
tabelaTipoPagto.setModel(model);
TableColumn col = tabelaTipoPagto.getColumnModel().getColumn(2);
col.setCellEditor(new TipoPagtoTableCellEditor());

How do this ? Any idea ?

thanks.
