编辑：由于下面的例子很长，我在下面做了一个最小的例子，以便更容易地看到问题：
在下面的例子中，计数器的预期值应该是 0、1 和 2，但事实并非如此。第一个表使用 tabular 制作，而出现错误的第二个表使用 tabulary 制作。
\documentclass[]{article}
\usepackage{tabulary}
\newcounter{mycounter}
\begin{document}
\arabic{mycounter} % should be 0
\begin{tabular}{cc}
a\stepcounter{mycounter} & b
\end{tabular}
\arabic{mycounter} % should be 1
\begin{tabulary}{\textwidth}{JJ}
a\stepcounter{mycounter} & b
\end{tabulary}
\arabic{mycounter} % should be 2, as we have only increased the counter once since the value was 1
\end{document}
当试图想出一个答案时此主题，我写了以下一段代码。它的目的是排版一些称为 sidenotes 的东西，它的编号应该或多或少地与脚注的编号一样。但是，出于某种原因，命令 \sidenote 似乎对每个注释调用两次，导致每个注释的编号增加了每个段落中的注释数（见下图）。有没有简单的方法可以解决这个问题（即我是否遗漏了一些简单的东西）？

答案1
tabularx我本来可以发誓我偷了试运行后重置 LaTeX 计数器的代码，但显然并非如此......
（请注意，您可能应该使用它\jobname.foo作为临时文件名，运行时它会覆盖该名称的任何文件，这有点可怕。
