我想使用横向模式，其中有一个表格。但是当我嵌入环境的开始和结束时，\newenvironment{lessonPlanner}会出现错误，但是如果我移动到环境的外部，就不会出现错误。\begin{landscape}\end{landscape}\begin{landscape}
具体来说
Runaway argument?
!File ended whlie scanning use of \TX@get@body,
我以前遇到过这种情况，不得不使用表格命令形式，但我不知道这是否适合景观，我想更好地理解这个问题
任何帮助都将不胜感激，谢谢。

答案1
错误是因为tabularx环境会提前扫描以拾取要排版的内容，并且需要\endtabularx直接查看才能实现此目的。在您的代码中，它隐藏在\end{lesson}命令中。
解决此问题的一个好方法是使用environ包及其\NewEnviron命令。这将设置一个新环境，但在一个代码块中完成，并\BODY使用 used 插入环境的内容。对于您的情况，您可以按如下方式使用它：
\RequirePackage{environ}
\NewEnviron{lesson}[3]{
\begin{landscape}
\begin{tabularx}{\linewidth}{ c | c | X | c }
Time & \mbox{Activity} & Description & Resources \\
\hline
\BODY
\end{tabularx}
\end{landscape}
} % end lesson
请注意，这与所附代码文档中的正常用法如何匹配，特别是现在您可以使用\begin{tabularx}...\end{tabularx}它来代替\tabularx...\endtabularx。
以下是完整代码。顺便说一句，我一直写成lessonPlannernot lessonPlaner。
