Edit2
usted tiene que comprobar también
JTable.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
JTable.getTableHeader().setReorderingAllowed(false);
Gracias Sr. mKorbel pero puede usted por favor mirar en mi código. ¿Hay algo malo con eso? Establecer el ancho a cero debe funcionar. –
@Ashish Pancholi, por favor, mira mi edición, ¿hablamos de lo mismo :-) – mKorbel
Gracias Sr. mKorbel. Ahora está claro después de ver su código de muestra. Caso resuelto. –
