可能是这样的：

\documentclass{article}
\usepackage{colortbl}
\usepackage{arydshln,graphicx,xcolor,array}

\begin{document}
  \arrayrulecolor{magenta}%
  \setlength{\arrayrulewidth}{1pt}%
  \begin{tabular}{c;{2pt/2pt}c|}
    \includegraphics[width=3cm]{example-image-a} & \includegraphics[width=3cm]{example-image-b}
  \end{tabular}
  \arrayrulecolor{blue}%
  \setlength{\arrayrulewidth}{1pt}%
  \begin{tabular}{c;{2pt/2pt}c}
    \includegraphics[width=3cm]{example-image-a} & \includegraphics[width=3cm]{example-image-b}
  \end{tabular}

\end{document}

如果您不介意使用tikz，您可以使用matrix的库tikz并以任何您喜欢的方式绘制线条。这种方法用途广泛。

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{matrix}

\begin{document}

\begin{tikzpicture}
\matrix (a)[row sep=0mm, column sep=0mm, inner sep=1mm,  matrix of nodes] at (0,0) {
            \includegraphics[width=3cm]{example-image-a} &
            \includegraphics[width=3cm]{example-image-b} &
            \includegraphics[width=3cm]{example-image-c}\\
            \includegraphics[width=3cm]{example-image-a} &
            \includegraphics[width=3cm]{example-image-b} &
            \includegraphics[width=3cm]{example-image-c}\\\\
        };
%

\draw[thick,red] (a-1-1.north east) -- (a-2-1.south east);
\draw[thick,densely dashed,blue] (a-1-2.north east) -- (a-2-2.south east);
\end{tikzpicture}

\end{document}
