Checkbox en JTable

[tambu10]

Tenias razon dackiller faltaba poner que esa columna sea editable. El único problema que falta resolver es, cuando ejecuto esa GUI (ventana grafica) se ve bien como deberia quedar, pero cuando ejecuto el sistema completo, al abrir esa ventana me la muestra mal, se ve todo gris, como si un fondo gris tapara dicha ventana.

El error que me tira es el sig:
