表格由多行文本单元格和一列图像单元格组成。每行中的图像位于一列内。但图像大小不同。希望将每幅图像在其单元格中水平和垂直居中。如何编写这样的代码？
代码如下：
\begin{table*}[ht]
\footnotesize
\caption{Some table}
\begin{center}
\label{sometable}
\begin{tabularx}{7.4in}{ p{2cm} | p{1.8cm} | p{1.8cm} | p{3.5cm} | p{3.5cm} | p{3.5cm} }
\hline
\textbf{Image} & \textbf{Detected} & \textbf{Indirectly Related} & \textbf{Sentences Generated by Model with Indirectly Related} & \textbf{Sentences Generated by Model without Indirectly Related} & \textbf{Standard Model} \\
\raisebox{-1.0\height}{\includegraphics[width=0.8in]{some image}} & Some text & Some text & Some text & Some text \\ \hline
\end{tabularx}
\end{center}
\end{table*}

你的问题有点不清楚。你应该提供一个完全的 最小工作示例（MWE），因为，即使\footnotesize您的表格大于普通文章的文本宽度。
如果您希望所有单元格垂直和水平对齐，可以使用前面m{...}带有 的列类型。为了方便起见，我创建了一种新的列类型。>{\centering\arraybackslash}M
不要center在环境内部使用环境figure，\centering而是使用，参见此处：
我应该对图形和表格使用 center 还是 centering ？
tabularxX如果你的表定义中没有列，那么它是无用的。
只是为了帮助改善您的问题，而不是真正回答，我试图纠正您的代码，并建议使用booktabs和的替代代码threeparttable。
\documentclass{article}
\usepackage{array}
\newcolumntype{M}[1]{>{\centering\arraybackslash}m{#1}}
\renewcommand{\arraystretch}{1.2}
\usepackage{booktabs}
\usepackage{threeparttable}
\usepackage{graphicx}
\usepackage{caption}
\begin{document}
\begin{table*}[ht]
\centering\footnotesize
\caption{Some table\label{sometable}}
\begin{tabular}{M{2.1cm}|M{1.4cm}|M{1.4cm}|M{1.4cm}|M{1.4cm}|M{1.4cm}}
\hline
\textbf{Image} & \textbf{Detected} & \textbf{Indirectly Related} & \textbf{Sentences Generated by Model with Indirectly Related} & \textbf{Sentences Generated by Model without Indirectly Related} & \textbf{Standard Model} \\
\includegraphics[width=0.8in]{example-image} & Some text & Some text & Some text & Some text \\
\includegraphics[width=0.5in]{example-image-a} & Another image & with another dimension & Some text & Some text \\
\includegraphics[width=0.7in]{example-image-b} & Another image again & with another dimension & Some text & Some text \\
\hline
\end{tabular}
\end{table*}
\begin{table*}[ht]
\centering\footnotesize
\caption{Some table with attempt at improvement\label{mytable}}
\begin{threeparttable}
\begin{tabular}{M{2.1cm}M{1.4cm}M{1.4cm}M{1.4cm}M{1.4cm}M{1.4cm}}

\textbf{Image} & \textbf{Detected} & \textbf{Indirectly Related} & \textbf{With IR}\tnote{a} & \textbf{Without IR}\tnote{b} & \textbf{Standard Model} \\
\midrule
\includegraphics[width=0.8in]{example-image} & Some text & Some text & Some text & Some text \\

\end{tabular}
\begin{tablenotes}
\item[a] Sentences Generated by Model \emph{with} Indirectly Related.
\item[b] Sentences Generated by Model \emph{without} Indirectly Related.
\end{tablenotes}
\end{threeparttable}

具有不同宽度的列\ tabularx的解决方案：X
