我将一些回归表保存为 tex 文件。然后当我尝试将其保存为 pdf 时，它最终被损坏了。然后当我尝试排版时，它显示：“！LaTeX 错误：环境表未定义。”
这是我的 tex 文件：

我对此真的很陌生，所以如果能得到任何帮助，我将不胜感激。如果我违反了提问的任何准则，请道歉并告诉我如何解决。提前致谢！
最好的，M.卡马尔
答案1
在以下示例中，我添加了缺失的 documentclass 以及 和\begin{document}。\end{document}我加载了geometry包以便获得较小的边距，并加载了longtable包以允许在表格内分页。为了使表格变窄（因为它超出了文本宽度），我使用了固定宽度p类型的列，允许在第一列中自动换行。为了使第一列的内容左对齐，我使用了 包 array和>{\raggedright\arraybackslash}。
\documentclass{article}
\usepackage{geometry}
\usepackage{longtable}
\usepackage{array}
\begin{document}
\def\sym#1{\ifmmode^{#1}\else\(^{#1}\)\fi}
