我不敢相信我在谷歌上找不到。我编程的每个JTable都会自动填充来自DB的数据,任何编辑都是通过监听器完成的,但现在出于测试目的,我只有一个简单的3x3表,我不知道如何在代码中手动选择一个单元格(为了测试目的更改bg颜色),比如table.cellAt(1,1).setBGcolor。。。

所以你的问题是“如何更改给定行和索引处单元格的背景颜色?”。
单元格的背景颜色取决于与单元格关联的渲染器。但是,您不能将渲染器与单元格相关联。你能做的是
getCellRenderer(int row, int column)
to return your own renderer因此,如果要更改给定单元格的背景颜色,则必须将表配置为使用自定义渲染器,并且必须将此自定义渲染器配置为使用您的背景颜色而不是此给定单元格的默认颜色(或者更改此特定单元格中的数据值,以便您的自定义渲染器知道它必须使用背景颜色)。
如何在代码中手动选择单元格?
table.changeSelection(行、列、false、false)
