我正在使用pgfplots（与优秀的matlab2tikz），pgfplotstable和subcaptionbox一起，并且由于某些无法解释的原因（至少对我来说），该命令\pgfplotsforeachungrouped似乎破坏了的标签\subcaptionbox- 即标签从变成(a)了(2subfigure)。
我试图让 MWE 保持简短，但我想根据答案包含一个用例片段，说明为什么我想要这个特定的命令组合（我想说，这并不太离谱）https://tex.stackexchange.com/a/34045/42225。
注释掉\pgfplotsforeachungrouped-command 会删除我的表格的（大部分）格式，但随后 -labels\subcaptionbox会再次起作用（注释掉命令的内容没有效果）。

答案1
\alph是一个将计数器的值打印为字母的宏，这会导致冲突，因为它是由您重新定义的。通常，子标题编号为a、b等，并使用 打印\alph{subfigure}。当\alph重新定义为时2，循环中的最后一个值\alph{subfigure}变为2subfigure。
将循环宏称为其他名称，这样\MyVar您的代码就可以正常工作。
