请不要booktabs与\hlines 和竖线组合使用。这不应该组合。您可以\cline在此处使用 代替\cmidrule，或者采用纯booktabs方法，如下所示：

这只是一个起点。表格太宽，不适合，但我不知道您的文档类别和常规设置，所以我不想在这上面花更多时间。到目前为止，表格还不是很清楚，因为您在某些地方使用多行，而在其他地方则没有。尽量保持一致。

答案2

作为 LaRiFaRi 答案的变体/补充......

在准备答案时，我假设页面为 A4 大小，文本边距为 25 毫米。由于表格使用 10 pt 大小的标准字体，比页面宽度宽，因此我在表格中使用较小的\footnoteseize字体，并\tabcolsep从默认字体减小6pt到5pt。使用同名包中的宏，\makecell我实现了更清晰、更合乎逻辑的（当然，在我看来）表格设置结构。

如果文档中使用了较大的字体，并且表格中的文本必须与主文本使用相同的字体，则考虑将表格方向更改为横向似乎是明智的。为此，似乎可以使用方便的包rotating并替换table in above MWE with itssidewaystable` 环境。
