Betreff	neue Zeile an Tabelle hängen

---

Hallo,
ich würde gerne eine Zeile an eine Tabelle hinzufügen wenn ich auf einen Button klicke. Ich habe ein kleines Programm geschrieben, das eine Tabelle und einen Button enthält. Leider schaffe ich es partout nicht, etwas anständiges in den ActionHandler zu schreiben.
Wäre über jede Hilfe dankbar.
