如何让图像在单元格内被一层空间包围

Question

\begin{tabular}[h]{|l|c|}
\hline
\multicolumn{2}{|l|}{Proving Rectangle}\\
\hline
4 right angles & \raisebox{-\totalheight}{\includegraphics[scale=0.3]{ProveRectangleA}}\\
\hline
Parallelogram with 1 right angle & \raisebox{-\totalheight}{\includegraphics[scale=0.3]{ProveRectangleB}}\\
\hline
\end{tabular} \end{center}

Answer 1

使用该cellspace包，您可以在图像周围实现空白边框。 \cellspacetoplimit可以\cellspacebottomlimit使用命令将其设置为您选择的长度setlength。在示例中，我还添加了一个不太冗长且略有不同的变体，使用adjustbox包和valign=t选项实现顶部对齐的图像。（比较第一幅和第二幅图像相对于左列相应行中的文本行的对齐情况。）

\documentclass{article}
\usepackage[demo]{graphicx}

\usepackage{cellspace}
\setlength\cellspacetoplimit{6pt}
\setlength\cellspacebottomlimit{6pt}

\usepackage[export]{adjustbox}

\begin{document}

\begin{tabular}{|l|Sc|}
  \hline
  \multicolumn{2}{|l|}{Proving Rectangle}\\
  \hline
  4 right angles & \raisebox{-\totalheight}{\includegraphics[scale=0.3]{ProveRectangleA}}\\
  \hline
  Parallelogram with 1 right angle & \includegraphics[scale=0.3,valign=t]{ProveRectangleB}  \\
  \hline
\end{tabular} 

\end{document}

Answer 2

您可以添加一个空行 \\ &

\documentclass{article}
\usepackage{graphicx}
\usepackage{mwe}


\begin{document}
   \begin{tabular}{|l|c|}
\hline
\multicolumn{2}{|l|}{Proving Rectangle}\\
\hline
4 right angles & \raisebox{-\totalheight}{\includegraphics[scale=0.3]{example-image-a}}\\
&\\ % <----------- added
\hline
Parallelogram with 1 right angle & \raisebox{-\totalheight}{\includegraphics[scale=0.3]{example-image-b}}\\
&\\ % <------------- added
\hline
\end{tabular} 

\end{document}
