表格环境中插入图片+文字的问题

Question

我不知道为什么文字会超出范围（如图所示）。提前感谢

\begin{center}
\begin{table}[h!]
  \centering
  \begin{tabular}{c|c|c|c}
    \hline
     \centering
   No. &  Pr & Po & Description \\ \hline
    1
    &
    \begin{minipage}{.3\textwidth}
      \centering
      \includegraphics[width=4.8cm,height=3cm]{Pictures.png}   
    \end{minipage}
    &
    \begin{minipage}{.3\textwidth}
       \centering
      \includegraphics[width=4.8cm,height=3cm]{Pictures.png} 
    \end{minipage}
    & 
    \begin{minipage}{.3\textwidth}
       \centering
        $\bullet$ st\ $\bullet$ st.
    \end{minipage}  
    \\ \hline

Answer 1

• 您的桌子比\textwidth：（4 x 0.3 \textwidth= 1.2 \textwidth）更​​宽
• 除了使用之外，minipage您还可以使用p{...}列类型
• 目前还不清楚，最后一栏的内容是什么，我怀疑它是一些列表

\documentclass{article}
%---------------- show page layout. don't use in a real document!
\usepackage{showframe}
\renewcommand\ShowFrameLinethickness{0.15pt}
\renewcommand*\ShowFrameColor{\color{red}}
%---------------------------------------------------------------%

\usepackage[export]{adjustbox}  % it load graphicx too
\usepackage{array}
\usepackage{enumitem}

\begin{document}
    \begin{table}[ht]
    \centering
\setlist[itemize]{nosep=0pt,
                 leftmargin=*,
                 label=\textbullet,
                 after=\end{minipage},                  % <---
                 before=\begin{minipage}[t]{\linewidth} % <---
                 }
\adjustboxset{width=.25\textwidth,valign=t, margin=0pt 3pt 0pt 3pt}
\begin{tabular}{|c|*{3}{>{\centering\arraybackslash}p{\dimexpr0.3\linewidth-2\tabcolsep}|}}
    \hline
No. &   Pr 
        &   Po 
            &   Description         \\ 
    \hline
1   &   \adjustimage{}{example-image-duck}%{Pictures.png}
        &   \adjustimage{}{example-image-duck}%{Pictures.png}
            &   \begin{itemize}
            \item   st.
            \item   st
                \end{itemize}       \\
    \hline
\end{tabular}
    \end{table}
\end{document}
