这是我尝试过的:
\begin{figure}[h!]
\begin{subfigure}[b]{0.2\textwidth}
\begin{tabular}{|c|}
\hline
3 \\
\hline
1 \\
\hline
4 \\
\hline
\end{tabular}
\newline
\vspace*{0.5cm}
\newline
\begin{tabular}{|c|}
\hline

\hline
7 \\
\hline

\hline
\end{tabular}
\caption{Input}
\end{subfigure}
\hfill
\begin{subfigure}[b]{0.2\textwidth}
\centering
\begin{tabular}{|c|}
\hline

\hline

\end{subfigure}
\hfill
\begin{subfigure}[b]{0.2\textwidth}
\centering
\begin{tabular}{|c|}
\hline

\hline

\hline

\hline
\end{tabular}
\caption{Multiplication}
\end{subfigure}
\hfill
\begin{subfigure}[b]{0.2\textwidth}
\centering
\begin{tabular}{|c|}
\hline

\hline

\hline

\hline
2 \\
\hline
7 \\
\hline
2 \\
\hline
\end{tabular}
\caption{Concatenation}
\end{subfigure}
\caption{xyz}
\label{fig:x}
\end{figure}
但这不是我想要的。我在居中第一个子图时也遇到了问题。
如能得到任何帮助我将非常感激。
答案1
您可以测量最高子图的高度和子标题的宽度。 的语法subcaption
与 的语法相同minipage
,因此您可以指定高度。
\documentclass{article}
\usepackage{subcaption}
\newlength{\subfigureht}
\newlength{\subfigurewd}
\begin{document}
\begin{figure}[!htp]
\settoheight{\subfigureht}{%
\begin{minipage}[b]{\textwidth}
\begin{tabular}{|c|}
\hline

\hline

\hline
4 \\
\hline
\end{tabular}
\endgraf\medskip
\begin{tabular}{|c|}
\hline
2 \\
\hline
7 \\
\hline

\hline
\end{tabular}
\endgraf\vspace{0pt}
\end{minipage}%
}
\addtolength{\subfigureht}{2\baselineskip}
\settowidth{\subfigurewd}{(m) Input}%
\begin{subfigure}[b][\subfigureht][s]{\subfigurewd}

试试这个代码。子图的解释在主图的标题中完成。(并替换了 s \newline
)
\documentclass[12pt,a4paper]{article}
\usepackage{subcaption}
\usepackage{graphicx}
\captionsetup{labelformat= empty, textfont=small}
\captionsetup[sub]{textfont=small}
\usepackage{showframe}% only to show margins

\caption{(a) input \, (b) `+' addition \, (c) `\times' multiplication \, (d) `\oplus' concatenation}
\label{fig:x}
\end{figure}
\end{document}
如果您想将符号添加到标题中,例如 \caption{\times}
在子图中。
答案3
这使用 tabularx 分别对齐表格和子标题。标题以 开始和结束\par
,因此您需要某种段落列类型,这也会均匀分布它们(而不是基于标题宽度)。
仅第一个表格需求放入保存箱中。此外,varwidth 不能很好地与 配合使用\newline
。
\documentclass{article}

\caption{xyz}
\label{fig:x}

\end{document}
此版本用于\raisebox
使 LaTeX 认为所有图像都是相同的大小(\ht0
和\dp0
)。
