我想在网格中的每个节点内放置两行文本，并希望它们居中。现在我知道这在其他线程中。例如，最自然的解决方案是与节点文本括号内的align=center换行符结合使用。\\
下面是图片和 MWE。如您所见，字母未居中，而数字居中。我试过：
align+\\text width，单独或与上述组合tabular节点文本括号内的环境- 删除
\scriptsize我使用的参数正如您所见，我使用嵌套的 for 循环创建一个以蛇形形式向上计数的网格。某些索引组（外部预定义）接收某些字母，我使用定义的命令实现这一点\mylabel。这个想法来自我的问题早些时候。但是，我就是无法让字母与下面一行中的数字居中对齐。

答案1
对齐很好，但有几个你看不到的不需要的空格。尝试将命令括\mylabel在 a 中\fbox，你会看到这些空格：
\fbox{\mylabel{\label}}\\[-5pt]
您可以执行以下操作来避免出现不需要的空格：

编辑：为了缩短编译时间，如果图片的其他部分不需要这些组，则可以通过这种方式更改宏（并删除现在不需要的组定义）会更快：
\newcommand{\mylabel}[1]
{%
\pgfmathtruncatemacro{\num}{#1}% <-- to prevent unwanted spaces
\scriptsize% you can put this here instead of inside each loop
\foreach\c in { 2,11,13,22,24,33,35,44,46,55,57,66,68,77,79,88} % GROUP C
{\ifnum \num = \c C\fi}% <-- to prevent unwanted spaces
\foreach\a in { 3, 4, 5, 6, 7, 8, 9,10,14,15,16,17,18,19,20,21, % GROUP A
25,26,27,28,29,30,31,32,36,37,38,39,40,41,42,43,
47,48,49,50,51,52,53,54,58,59,60,61,62,63,64,65,
69,70,71,72,73,74,75,76,80,81,82,83,84,85,86,87}
{\ifnum \num = \a A\fi}% <-- to prevent unwanted spaces
\foreach\h in {12,23,34,45,56,67,78} % GROUP H
{\ifnum \num = \h H\fi}% <-- to prevent unwanted spaces
\ifnum \num = 89 O\fi % GROUP O
}
笔记：也许我应该在之前的回答中指出这一点。
