将图片下方的标题与子浮动对齐

Question

子浮动图形下方的标题未与相应图像对齐。有什么解决办法吗？

\documentclass{article}
\usepackage{graphicx}
\usepackage{lipsum}

\usepackage{subfig}

\begin{document}
\lipsum[1]

\begin{figure}[h]%
    \captionsetup{width=0.8\textwidth}
    \centering
    \subfloat[Subcaption 1]{{\label{fig_1}\includegraphics[width=3cm,keepaspectratio]{example-image-a} }} %
    \quad
    \subfloat[Subcaption 2]{{\label{fig_2}\includegraphics[width=3cm,keepaspectratio]{example-image-b} }}
\end{figure}

\lipsum[1]
\end{document}

Answer 1

subfigure 包提供的环境subcaption做得更好。

可以只设置字幕，\captionsetup[sub]{<options>}不受主角的字幕设置干扰。

\documentclass{article}
\usepackage{graphicx}
\usepackage{lipsum}

\usepackage{subcaption} % added <<<<<<<<<<<


\begin{document}
    \lipsum[1]  

\noindent   \begin{figure}[h]%  
    \captionsetup{width=0.8\textwidth}
    \captionsetup[sub]{font={sf,it}}
    \centering
    \begin{subfigure}[c]{3cm}
        \includegraphics[width=3cm,keepaspectratio]{example-image-a}
        \caption{Subcaption 1}  \label{fig_1}
    \end{subfigure}
    \quad
    \begin{subfigure}[c]{3cm}
        \includegraphics[width=3cm,keepaspectratio]{example-image-b}
        \caption{Subcaption 2}  \label{fig_2}
    \end{subfigure} 
    \caption{\lipsum[4]}
\end{figure}


See figure \ref{fig_1}.
    
    \lipsum[1]
