无法使用 parbox 将表格中的数字居中

Question

我正在尝试创建一个以四个数字居中的表格，并且下一行的文本也应居中。

如您所见，parboxes 未居中，我尝试了几种方法来解决这个问题，但都无法解决。感谢您的建议！

\begin{table}
\centering
\caption{xxx}
\label{tab:xxx}
\begin{tabular}{p{2.5cm}p{2.5cm}p{2.5cm}p{2.5cm}} %
\hline
\parbox[c]{1em}{\includegraphics[height=0.5in]{example-image-b}}
  & \parbox[c]{1em}{\includegraphics[height=0.5in]{example-image-b}}
  & \parbox[c]{1em}{\includegraphics[height=0.5in]{example-image-b}}
  & \parbox[c]{1em}{\includegraphics[height=0.5in]{example-image-b}}\\
 \multicolumn{1}{|c|}{Part} & \multicolumn{1}{|c|}{Impactor} &  \multicolumn{1}{c|}{Scalp} &\multicolumn{1}{c|}{Sphere}\\
x & x & x & x\\
x & x & x & x\\
x & x & x & x\\
\end{tabular}
\end{table}

Answer 1

简单就是力量。那么只使用 怎么样\hfil？

\documentclass{article}
\usepackage{graphicx}
\begin{document}
\begin{tabular}{|p{2.5cm}|p{2.5cm}|p{2.5cm}|p{2.5cm}|} %
\hfil\includegraphics[height=0.5in]{example-image-a} &
\hfil\includegraphics[height=0.5in]{example-image-b} &
\hfil\includegraphics[height=0.5in]{example-image-c} &
\hfil\includegraphics[height=0.5in]{example-image} \\
\hfil Part & \hfil Impactor & \hfil Scalp & \hfil Sphere \\
\end{tabular}
\end{document}

Answer 2

我不确定我是否正确理解了你的问题，但让我尝试一下：

代码相当简单：

\documentclass{article}
\usepackage{graphicx}
\usepackage{array, booktabs}
\newcolumntype{C}[1]{>{\centering\arraybackslash}p{#1}}

\begin{document}
    \begin{table}
\centering
\caption{xxx}
    \label{tab:xxx}
\begin{tabular}{*{4}{C{2.5cm}}} %
    \toprule
\includegraphics[height=0.5in]{example-image-b}
    &   \includegraphics[height=0.5in]{example-image-b}
        &   \includegraphics[height=0.5in]{example-image-b}
            &   \includegraphics[height=0.5in]{example-image-b}     \\
Part    &   Impactor    &   Scalp   &   Sphere                      \\
x   & x & x & x\\
x   & x & x & x\\
x   & x & x & x
\end{tabular}
    \end{table}
\end{document}
