beamer我有一个如下所示的框架：

 \begin{tabular}{ccccc}
  \includegraphics[width=.15\textwidth]{imgs/a1} & \pause
  \includegraphics[width=.15\textwidth]{imgs/a2} & \pause 
  \includegraphics[width=.15\textwidth]{imgs/a3} & \pause 
  \includegraphics[width=.15\textwidth]{imgs/a4} & \pause 
  \includegraphics[width=.15\textwidth]{imgs/a5} \\
 \end{tabular}

 \begin{tabular}{ccccc}
  \includegraphics[width=.15\textwidth]{imgs/b1} & \pause       \includegraphics[width=.15\textwidth]{imgs/b2} & \pause       \includegraphics[width=.15\textwidth]{imgs/b3} & \pause       \includegraphics[width=.15\textwidth]{imgs/b4} & \pause       \includegraphics[width=.15\textwidth]{imgs/b5} \pause \\
 \end{tabular}

我想要做的是按顺序显示第二个表中的图像从右到左，也就是说，在第一个表格显示后，我希望它b5首先出现（在最右边的位置），然后b4，等等。

有没有一种“优雅”的方式来做到这一点（即不滥用\only<>）？tabular这样的环境合适吗？

您可以手动指定暂停次数：

\documentclass{beamer}
\begin{document}
\begin{frame}
 \begin{tabular}{ccccc}
  \includegraphics[width=.15\textwidth]{lion.jpg} & \pause 
  \includegraphics[width=.15\textwidth]{lion.jpg} & \pause 
  \includegraphics[width=.15\textwidth]{lion.jpg} & \pause 
  \includegraphics[width=.15\textwidth]{lion.jpg} & \pause 
  \includegraphics[width=.15\textwidth]{lion.jpg}           \\
 \end{tabular}

\pause[10]
 \begin{tabular}{ccccc}
  \includegraphics[width=.15\textwidth]{lion.jpg} &  \pause[9]  
  \includegraphics[width=.15\textwidth]{lion.jpg} &  \pause[8] 
  \includegraphics[width=.15\textwidth]{lion.jpg} &  \pause[7]  
  \includegraphics[width=.15\textwidth]{lion.jpg} &  \pause[6] 
  \includegraphics[width=.15\textwidth]{lion.jpg}    \pause[5]\\
 \end{tabular}

% \pause[11]   % If you need to add more overlays after the images sequence you need to
% text         % specify the number of the first pause and then move on with normal
%              % pauses again, as shown in the commented code
% \pause
% text

\end{frame}
\end{document}

对此来说，环境tabular并不是必需的。此外，您可以使用循环\foreach来稍微自动化一些。

代码

\documentclass{beamer}
\usepackage{pgffor}
\usepackage{mwe} % provides images used in this example

\begin{document}
\begin{frame}
Left to right
\begin{center}
  \foreach \img[count=\i] in {a,b,c} {
    \visible<\i->{\includegraphics[width=.15\textwidth]{image-\img} \hskip15pt}
  }
\end{center}

\bigskip

Right to left
\begin{center}
  \foreach \img[count=\i] in {a,b,c} {
    \pgfmathtruncatemacro{\r}{7-\i} % Here, 7 = 6 + 1 = number of last slide + 1
    \visible<\r->{\includegraphics[width=.15\textwidth]{image-\img} \hskip15pt}
  }
\end{center}
\end{frame}

\end{document}
