Answer 1

好的，面对@StefanH 发现您缺失的}，并在@Mico 的解决方案的基础上，我尝试通过重构您的表格来扩展主题。我向您的解决方案添加了以下包：

• array-> 有\extrarowheight
• booktabs-> 针对花哨的规则
• siunitx以适当的间距排版单元。

此外，为了避免过多，$我定义了一种新的列类型，可以自动为您插入。

因此，经过一些清理后，下面是代码，后面是结果。您会注意到我使用了更少的行，因为这样信息对我来说感觉分组更好，也更易读：

\usepackage{array,booktabs,multirow}
\usepackage{siunitx}
