在数组环境中更改单元格对齐方式

谁能告诉我如何在数组环境中对齐字母 A、B、C、D 和 E，以便我可以将它们分别移动到黄点？

答案1

通过确定边界框顶部周围的绘图基线，可以实现 A、B、C、D 和 E 与绘图顶部所需的垂直对齐：

添加了两个包：array和booktabs，其中定义了\tikzset用于对齐图标签（A、B、...、E）和图顶部的样式。此外，\plotsset对于所有图，在序言中只定义了 1，因为它们在所有这些图中都是相等的。这样代码就更简洁了。构造 $\begin{array} ...\end{array} , which intention/benefits are not clear to me, is replaced withtabular` 环境。

可以看出，所有\raisebox框都被省略了。表格设计中也包含一些小的变化：用addlinespace从booktabs确定表格行之间的空间，scale可以省略而不会对图产生明显变化，从移动tikzpicture到axes更合适的位置（关于图中字体的缩放）。

答案2

你应该降低 将stikzpicture乘以 their \height（或将其提高-\height），以及对基线跳过的修正，在 下，array存储在 中\normalbaselineskip。由于tikzpicture的边框周围有更多空白，我们可以将其\normalbaselineskip增加到1.5\normalbaselineskip：
