我有一个表，表模型包含一些名称，一个CellRenderer扩展了我制作的包含JButton的面板。 Everythign的工作原理非常好，除了单击按钮时，只要按住JButton，单元格中的值就会消失！在面板和渲染器下面。有任何想法吗？

感谢您的任何想法。
最佳答案
不要设置/修改任何JComponent，它的值在XxxRenderer内，不要更改值的状态（来自XxxTableModel）XxxRenderer只是装饰器而不是值生成器，
因为单元格值（在XxxRenderer中）是存储在XxxTableModel中的可重复使用的值，要在XxxTableModel中设置此值，
不要将JComponents存储在XxxTableModel中，仅存储其渲染值
