在 Pgfplotstable 中使用 Slashbox/Diagbox

Question

我有一个这种形式的 csv 文件

,0.01,0.1,1.0,10.0,100.0
0,0.3837,0.8259,0.9386,0.9386,0.9386
1,0.3837,0.9464,0.9386,0.9386,0.9386
2,0.3976,0.95,0.9386,0.9386,0.9386
3,0.8259,0.9386,0.9386,0.9386,0.9386
4,0.9464,0.9386,0.9386,0.9386,0.9386

我已成功使用 Pgfplotstable 包将其作为表格插入我的 latex 文件中。这是屏幕截图：

我的问题是我想将最左上角的单元格（当前为空）设为具有两个元素 A 和 B 的对角线单元格。A 表示最左行，B 表示最上列。我知道我必须使用 slashbox 或 diagbox 来执行此操作，但我不知道如何在 pgfplotstable 中使用它。这是表格的工作示例。

您几乎已经完成了。我刚刚将其添加到before row密钥中。
