我发现https://stackoverflow.com/a/8493016/53897可以工作。
添加代码的方法是在导航器中右键单击JTable，然后选择“代码定制器”。在将new javax.swing.JTable()下拉框更改为“自定义创建”的行中，您现在可以编辑该片段，包括添加{...@Override public void changeSelection(...)...}所需的内容。
标准 Swing 有什么问题JTable？DefaultTableModel
确定缺少一些关于生产代码的想法（让事情变得更好）......，选择所有用于编辑器，单元格对齐，背景，前景，剥离，字体，外观和感觉等......（大多数自定义外观和感觉没有' t 与 Netbeans Swing 框架中的内置组件托盘一起正常工作），
SwingX 有用于 Netbeans 的组件托盘，更好和最安全的方式，也许你看过......
