Soy novato de Swing.

Quiero actualizar la tabla después de hacer clic en el botón (botón Listo). Creo que los datos son correctos pero la pantalla no funciona.

Los siguientes son explicaciones de mi programa.

marque checkBoxes y haga clic en el botón Listola capa inferior debería cambiar.no hay principal

Este es mi código:
