JTable – 布尔单元格类型 – 背景

我正在使用带有JTable的Nimbus L&F,它有一个布尔(复选框)元素作为其列之一。

带有复选框的Nimbus JTable

我遇到的问题是布尔列不遵循Nimbus L&F中存在的自然行背景替换。

这是合成器安装的渲染器中的一个错误,快速破解是强制渲染复选框opacity为true:

  ((JComponent) table.getDefaultRenderer(Boolean.class)).setOpaque(true); 

嗯,我有相反的问题,检查一下,真的没有人可以没有代码示例,也许有人可以使用TableCellRenderer使用未选择的AlternateTableColor

Nimbus默认值

我知道它是旧post,但对于其他搜索者:我使用jxtable()并解决了这个问题:)
