使用命令引用浮点数时\cref，有时可能会产生错误的排版。当包含子浮点数时尤其如此。
例如，当我们有浮点数 1 和两个子浮点数时，范围1a and 2 to 5将被误认为来自1a to 5。此外，如果源代码引用中同时包含1a和1b，则应该提及源代码中包含的所有子浮点数，而不仅仅是其中一个（参见第 2 点）。排版输出如下所示：
此输出是使用以下源代码生成的：
\documentclass[twocolumn]{report}
\usepackage{float}
\usepackage{subfloat}
\usepackage{caption}
\usepackage{cleveref}
\usepackage{paralist}
\begin{document}
\begin{subfigures}
% Subfigure 1
\begin{figure}[H]
\centering
\fbox{\Huge Figure 1a}
\caption{Caption 1}
\label{fig1a}
\end{figure}
% Subfigure 2
\begin{figure}[H]
\centering
\fbox{\Huge Figure 1b}
\caption{Caption 1b}
\label{fig1b}
\end{figure}
\end{subfigures}
% Figure 2

Figures are correctly cited for different citation formats such as:
\begin{enumerate}
\item Multiple: \textbf{\cref{fig5,,fig3,,fig4,,fig2}}
\item Range: \textbf{\cref{fig5,fig3,fig4}}
\item Multiple and range: \textbf{\cref{fig2,fig4,fig3,fig6}}
\end{enumerate}
\vspace{5mm}
But once subfigures are included, some citations formats do not work:
\begin{enumerate}
\item Multiple (works): \textbf{\cref{fig3,,fig4,,fig2,,fig1a}}
\item Range: \textbf{\cref{fig1a,fig1b,fig5,fig3,fig4}} (the output should be \textbf{figs. 1a to 1b and 3 to 5})
\item Multiple and range: \textbf{\cref{fig1a,fig2,fig4,fig3,fig6}} (the output should be \textbf{figs. 1a, 2 to 4 and 6})
\end{enumerate}
\end{document}
我已经有了一个可以缓解该问题的解决方案，但是与上述预期的输出并不相同。
答案1
我们可以定义新的浮点类型（subfig）cleveref
\crefformat{subfig}{fig. #1}
\crefrangeformat{subfig}{figs. #1 to #2}
\crefmultiformat{subfig}{figs. #1}{ and #1}{, #1}{ and #1}
\crefrangemultiformat{subfig}{figs. #1 to #2}{}{}{}
然后在序言中我们定义一个新命令：
\newcommand{\labelsf}[1]{ \label[subfig]{#1} } % a new command for labeling subfigures
labelsf现在可以用来标记子图。
完整源代码如下所示：
\documentclass[twocolumn]{report}
\usepackage{float}
\usepackage{subfloat}
\usepackage{caption}
\usepackage{paralist}
\usepackage{cleveref}
\crefformat{subfig}{fig. #1}
\crefrangeformat{subfig}{figs. #1 to #2}
\crefmultiformat{subfig}{figs. #1}{ and #1}{, #1}{ and #1}
\crefrangemultiformat{subfig}{figs. #1 to #2}{}{}{}
\newcommand{\labelsf}[1]{ \label[subfig]{#1} } % a new command for labeling subfigures
\begin{document}
\begin{subfigures}
% Subfigure 1
\begin{figure}[H]
\centering
\fbox{\Huge Figure 1a}
\caption{Caption 1}
\labelsf{fig1a}
\end{figure}
% Subfigure 2
\begin{figure}[H]
\centering
\fbox{\Huge Figure 1b}
\caption{Caption 1b}
\labelsf{fig1b}

cref现在可以正确引用子图，但是该解决方案的缺点是：
- 我们无法通过双击浮点数的标签来找到它的用法，也无法通过单击浮点数的标签来找到浮点数的源代码
- 浮标的名称有时会重复两次，这是多余的
