我正在使用 2 列IET模板我遇到了表格問題。即，即使表格本身是單列，表格的標題也會延伸到兩列。我已經設定了一個虛擬項目使用 MWE .tex 檔案來示範此問題：
\documentclass{cta-author}
\begin{document}
\supertitle{Test}
\title{Test}
\author{\au{First Author$^{1}$}, \au{Second Author$^{2\corr}$}, \au{Third Author$^{3}$}}
\address{\add{1}{First Department, First University, Address, City, Country Name}
\add{2}{Second Company Department, Company Address, City, Country Name}
\add{3}{Third Department, Third University, Address, Country Name}
\add{4}{Current affiliation: Fourth Department, Fourth University, Address, Country Name}
\email{[email protected]}}
\begin{abstract}
In the beginning the Universe was created. This had made many people very angry and has been widely regarded as a bad move.
\end{abstract}
\maketitle
\section{Figure}
Figures work fine as seen in Figure \ref{fig:sample}.
\begin{figure}
\centering
\includegraphics[width=\linewidth]{example-image-a}
\caption{This is a fairly long caption that doesn't actually provide any relevant, helpful, or indeed at all useful information about the figure in question.}
\label{fig:sample}
\end{figure}
\section{Table}
However, table captions extend over two columns even when the table itself is in a single column as seen in Table \ref{tab:sample}.
\begin{table}
\caption{This is another long and unhelpful caption that doesn't actually say anything about the below table but it does helpfully demonstrate the problem being discussed. Notice the table itself is appropriately placed and centred but the caption extends over both columns.}
\label{tab:sample}
\centering
\begin{tabular}{c|c}
1 & 2 \\
3 & 4
\end{tabular}
\end{table}
\end{document}
（我無法貼上類別文件本身，因為它打破了 30k 字元的限制。）
我需要在類別文件中修復什麼才能解決這個問題？我想避免在所有表格標題中新增手動換行符。
答案1
該類cta-author具有table.
\documentclass{cta-author}
\usepackage{lipsum} % for filler text
\begin{document}
\supertitle{Test}
\title{Test}
\author{\au{First Author$^{1}$}, \au{Second Author$^{2\corr}$}, \au{Third Author$^{3}$}}
\address{\add{1}{First Department, First University, Address, City, Country Name}
\add{2}{Second Company Department, Company Address, City, Country Name}
\add{3}{Third Department, Third University, Address, Country Name}
\add{4}{Current affiliation: Fourth Department, Fourth University, Address, Country Name}
\email{[email protected]}}
\begin{abstract}

\section{Table}
However, table captions extend over two columns even when the table itself is in a single column as seen in Table \ref{tab:sample}.
\begin{table}
\processtable{This is another long and unhelpful caption that doesn't actually say anything
about the below table but it does helpfully demonstrate the problem being
discussed. Notice the table itself is appropriately placed and centred but the
caption extends over both columns.\label{tab:sample}}
{\makebox[\columnwidth]{\begin{tabular}{c|c}
1 & 2 \\
3 & 4
\end{tabular}}}{}
\end{table}
\lipsum
\end{document}
實際上，標題的排版寬度與表格相同（出於我無法理解的原因），所以我用\makebox[\columnwidth]{...}.
