Mit dieser App kann der Fahrer eine Fahrt und einen Fahrer anfordern, um die Anfrage zu akzeptieren. In dieser Tabellenansicht sind die Fahrten, die die Fahrer (2) angefordert haben.TableViewController aktualisiert die Zellen nicht
Kann Tabellenzeilen nicht aktualisieren, jede Hilfe wäre wünschenswert.
