我正在尝试使用 arydshln 在表格中实现虚线。但是，该命令似乎无法正常工作，因为虚线不是从上到下绘制的，也就是说，在顶部看起来有点怪异。有人知道为什么这可能无法正常工作吗（或者是否可能与另一个包发生冲突？）。提前谢谢！

答案1
arydshln这似乎是和之间的不兼容性\hline\hline。
作为一种解决方法，我们可以使用{NiceTabular}它来nicematrix轻松绘制虚线规则，方法是使用垂直规则[tikz=dashed]说明符的选项|（版本≥6.24）。
使用 键first-row，第一行将不会绘制垂直线。

也可以;用标准命令定义新的列类型\newcolumntype（为了易读）：
\newcolumntype{;}{|[tikz=dashed]}
答案2
不太清楚，你的问题是什么？第一个表格行中没有垂直虚线，而第二个表格行中的垂直虚线不完整？
不过，我想知道为什么您使用混合
booktabs规则和双\hlines。\hline如果使用两个 s的话\toprule，印刷效果会更好（和更专业）\bottomrule。您可以考虑使用
tabularray包来编写表格。通过使用它，表格的代码更加一致，并且从表格的顶部到底部绘制虚线：
