我正在尝试实施这个解决方案： https://tex.stackexchange.com/a/418261/194338 或者这个解决方案： https://tex.stackexchange.com/a/416838/194338
但在我的例子中，两种方法都失败了。下面是一个最小示例：
\documentclass{article}
\usepackage{subcaption}
\usepackage{cleveref}
\crefrangelabelformat{figure}{#3#1#4 to #5\crefstripprefix{#1}{#2}#6}
\crefmultiformat{figure}%
{\edef\mycrefprefixinfo{#1}figs.~#2#1#3}%
{ and~#2\crefstripprefix{\mycrefprefixinfo}{#1}#3}% <- cannot access \mycrefprefixinfo when there is a range created
{, #2\crefstripprefix{\mycrefprefixinfo}{#1}#3}%
{, and~#2\crefstripprefix{\mycrefprefixinfo}{#1}#3}
\begin{document}
\cref{fig:test:1,fig:test:2,fig:test:3} % works: figs. 1a to c
\cref{fig:test:1,fig:test:3} % works: figs. 1a and c
\cref{fig:test:1,fig:test:3,fig:test:4} % works: figs. 1a, c, and d
\cref{fig:test:1,fig:test:2,fig:test:3,fig:test:5} % fails, should be figs. 1a to c and e
\begin{figure}
\centering
{\phantomsubcaption\label{fig:test:1}}%
{\phantomsubcaption\label{fig:test:2}}%
{\phantomsubcaption\label{fig:test:3}}%
{\phantomsubcaption\label{fig:test:4}}%
{\phantomsubcaption\label{fig:test:5}}%
\caption{General caption}
\end{figure}
\end{document}
基本上，当它创建一个范围时，它似乎会失败。从我的测试来看，当有一个范围时，该参数\mycrefprefixinfo在 \crefmultiformat 的第三个参数中不再可访问
答案1
因此根据@AndrewSwann 的评论和@AndrewSwann 的更新答案：为子图引用对定制 cleveref：[1a 和 b] 而不是 [1a 和 1b]
需要进行两处修改：更改\edef为并添加里面\xdef变量的定义：\mycrefprefixinfo\crefrangelabelformat
\crefrangelabelformat{figure}%
{\xdef\mycrefprefixinfo{#1}#3#1#4 to #5\crefstripprefix{#1}{#2}#6}
\crefmultiformat{figure}%
{\xdef\mycrefprefixinfo{#1}figs.~#2#1#3}%
{ and~#2\crefstripprefix{\mycrefprefixinfo}{#1}#3}%
{, #2\crefstripprefix{\mycrefprefixinfo}{#1}#3}%
{, and~#2\crefstripprefix{\mycrefprefixinfo}{#1}#3}
根据用例，可能还需要重新定义\crefrangemultiformat
如果仅调用，而不调用，则对于上述代码，需要\mycrefprefixinfo在里面添加变量的定义，这会将 的定义放在全局空间中。\crefrangelabelformat\cref{fig:test:1,fig:test:2,fig:test:3,fig:test:5}\cref{fig:test:1,fig:test:3}\mycrefprefixinfo
