Java GUI表将某些行添加到监视列表

好的，我正在设计一个应用程序，它将被许多使用JTable的用户使用，其中表的数据是使用JDBC拉入的。我正在考虑添加一个监视列表，以便用户可以在GUI中监视表中的某些行。这里是我的问题，因为我正在从JDBC中提取表的数据，所以我不需要为使用该应用程序的每个用户创建一个数据库MySql表，这样一个用户就可以向监视列表中添加行，而其他用户可以向监视列表中添加其他行，并排除其他用户可能已经包含在监视列表中的行。因为我的解决方案是在数据库中为监视列表的值添加一个额外的列，如果该值为true，则只显示这些行，如果该值为true，则不显示。但这个解决方案涉及为每个用户创建一个数据库表，这不是我想要的，而是将这些行添加到监视列表的另一种方法
