Как исправить эту ошибку?

Здравствуйте!
В последнем методе контроллера возникает ошибка:
'setCellFactory(javafx.util.Callback,javafx.scene.control.TableCell>)' in 'javafx.scene.control.TableColumn' cannot be applied to '(javafx.scene.control.cell.PropertyValueFactory)'
Подскажите, пожалуйста, как её исправить?
