使用指令引用浮點數時\cref，有時可能會產生不正確的排版。當包含子浮點時尤其如此。
一個例子是當我們有 float 1 和兩個子 float 時；該範圍1a and 2 to 5將被誤認為是來自1a to 5。另外，如果1a和都1b包含在原始碼引用中，則應該提及原始程式碼中包含的所有子浮點，而不僅僅是其中之一（請參閱第 2 點）。排版輸出如下所示：
此輸出是使用以下原始程式碼產生的：
\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
\begin{figure}[H]

\fbox{\Huge Figure 2}
\caption{Caption 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}
我已經有了一個可以緩解問題的解決方案，但與上面的預期輸出不同。
答案1
我們可以定義新的浮點類型 ( 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}{}{}{}
然後在序言中我們定義了一個新指令：
\newcommand{\labelsf}[1]{ \label[subfig]{#1} } % a new command for labeling subfigures
labelsf現在可用於標記子圖。
完整的原始碼如下所示：
\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

cref現在將正確引用子圖，但此解決方案的缺點是：
- 雙擊標籤無法找到float的用法，點選標籤也找不到float源碼
- 浮點數的名稱有時會重複兩次，這是多餘的
