![箭头显示多行范围](https://linux22.com/image/406633/%E7%AE%AD%E5%A4%B4%E6%98%BE%E7%A4%BA%E5%A4%9A%E8%A1%8C%E8%8C%83%E5%9B%B4.png)
我正在创建一个具有不同multirow
高度的表格。我希望箭头延伸到文本上方/下方以显示适用范围multirow
。下面是一个简单的示例,其中所需的箭头为红色。
对于三行(参见黑色箭头),可能有一个比较 hack 的解决方案,但如果有一种方法可以自动创建箭头,而不管行数是多少,那就太理想了。
MWE 中的表格很简单,可以用 完全绘制tikz
,但预期的应用使完整tikz
实现变得不切实际。

为什么 TikZ 解决方案不切实际?
这是一个使用 TikZ 矩阵的解决方案,可以轻松扩展为任意数量的行。

\usepackage{tikz}
