latex - LaTeX 中的迭代

Question

我想使用一些迭代控制流程来简化以下 LaTeX 代码。

  \begin{sidewaystable}
  \caption{A glance of images}
  \centering
  \begin{tabular}{| c ||c| c| c |c| c|| c |c| c|c|c| }
  \hline
  \backslashbox{Theme}{Class} &\multicolumn{5}{|c|}{Class 0} & \multicolumn{5}{|c|}{Class 1}  \\
  \hline

  \hline
          1 &
          \includegraphics[scale=2]{../../results/1/0_1.eps}
          &\includegraphics[scale=2]{../../results/1/0_2.eps}
          &\includegraphics[scale=2]{../../results/1/0_3.eps}
          &\includegraphics[scale=2]{../../results/1/0_4.eps}
          &\includegraphics[scale=2]{../../results/1/0_5.eps}
          &\includegraphics[scale=2]{../../results/1/1_1.eps}
          &\includegraphics[scale=2]{../../results/1/1_2.eps}
          &\includegraphics[scale=2]{../../results/1/1_3.eps}
          &\includegraphics[scale=2]{../../results/1/1_4.eps}
          &\includegraphics[scale=2]{../../results/1/1_5.eps}      \\
  \hline

  ...  % similarly for 2, 3, ..., 22

  \hline
          23 &
          \includegraphics[scale=2]{../../results/23/0_1.eps}
          &\includegraphics[scale=2]{../../results/23/0_2.eps}
          &\includegraphics[scale=2]{../../results/23/0_3.eps}
          &\includegraphics[scale=2]{../../results/23/0_4.eps}
          &\includegraphics[scale=2]{../../results/23/0_5.eps}
          &\includegraphics[scale=2]{../../results/23/1_1.eps}
          &\includegraphics[scale=2]{../../results/23/1_2.eps}
          &\includegraphics[scale=2]{../../results/23/1_3.eps}
          &\includegraphics[scale=2]{../../results/23/1_4.eps}
          &\includegraphics[scale=2]{../../results/23/1_5.eps}      \\
  \hline

  \end{tabular}
  \end{sidewaystable}

我了解到forloop package提供for循环。但我不知道如何将其应用到我的案例中？或者其他不通过forloop的方法？

<小时/>

如果我还想简单地另一个类似的情况，唯一的区别是目录不是从 1, 2, 到 23 运行，而是以某种任意顺序运行，例如 3, 2, 6, 9,... ，甚至是诸如 dira、dirc、dird、dirb 之类的字符串列表，...那么如何将 LaTeX 代码放入循环中呢？

Answer 1

您可以使用pgf提供的工具pgffor包。基本语法是:

\foreach \n in {0,...,22}{do something}

值得注意的是，这个 for 循环不限于整数，例如:

\foreach \n in {apples,burgers,cake}{Let's eat \n.\par}
