Nimbus风格下Swing JTable布尔单元格背景色设置异常问题

问题场景 #

在NetBeans 15、Sun JDK 19.0.1环境下开发Swing GUI，尝试为JTable行设置自定义背景色时，发现布尔类型单元格的背景无法与其他单元格保持一致。

已尝试方案 #

• 自定义TableCellRenderer，设置背景色为红色，但布尔单元格显示白色；开启setOpaque(true)后，布尔单元格呈现交替背景色。
• 重写JTable的prepareRenderer方法，出现完全相同的现象。

进一步观察 #

• Nimbus Look&Feel会自动启用交替行颜色，修改UIManager的Table.alternateRowColor属性为绿色后，布尔单元格背景变为交替绿色。
• 移除Nimbus可以解决该问题，但会导致UI样式过时。
• 选中行时，布尔单元格能正常显示正确的背景色。
• 查阅setBackground()文档发现，部分Look&Feel可能会忽略该属性。目前结论：无论如何配置，仅能修改非交替行的布尔单元格背景，选中行除外。

疑问 #

• 是否遗漏了关键的配置步骤？
• 能否禁用Nimbus的交替行颜色功能？
• 这是否是Nimbus Look&Feel的已知问题？
