Ich bin Newbie von Swing.

Ich möchte die Tabelle aktualisieren, nachdem Sie auf die Schaltfläche (Fertig) geklickt haben. Ich denke, die Daten sind korrekt, aber der Bildschirm funktioniert nicht.

Das Folgende ist eine Erklärung meines Programms

ktivieren Sie die Kontrollkästchen und klicken Sie auf "Fertig" Die unterste Ebene sollte sich ändern.s gibt kein Haupt

Dies ist mein Code:
