Sortiertabelle ist falsch, wenn die Sortiertaste mehr als einmal gedrückt wird?
Ich habe hier ein Problem. Ich erstelle ein Programm, um der Tabelle Daten hinzuzufügen und sie zu sortieren, wenn ich die Taste drücke. Wenn ich den Sortierknopf einmal drücke, ist es nicht falsch. aber wenn ich erneut drücke, ist es falsch. warum also? Bitte hilf mir. Das ist der Code.

Vielen Dank. Und Entschuldigung für mein schlechtes Englisch.
