我正在测试这个答案中提供的一个很好的解决方案如何将列表中的背景颜色裁剪为代码中最长的一行
然而，我碰巧使用的是longtable，而不是标准tabular。我不认为会有什么不同。
但出于某种原因，给出的代码在内部使用时会产生错误longtable 。一切都完全相同。唯一的区别是tabular，我没有使用，而是将其更改为longtable，现在出现了语法错误。
这是 MWE（与上面链接的代码相同，我只是改为tabular，longtable因为在我的代码中，我实际上将其用于longtable所有内容）
\documentclass[11pt]{article}
\usepackage[T1]{fontenc}
\usepackage{color}
\usepackage{listings}
\usepackage{tcolorbox}
\tcbuselibrary{listings}
\usepackage{longtable}
\definecolor{bg}{RGB}{240,240,240}
\begin{document}
\begin{longtable}{|p{0.8\textwidth}|p{.2\textwidth}|}\hline
\begin{tcblisting}{colback=bg,size=minimal,hbox,
listing only,listing options={language=Mathematica}}
f[x_] := Sin[x];
Plot[f[x],{x,-Pi,Pi}]
\end{tcblisting}
&
plot command
\\\hline
\end{longtable}
\end{document}
错误是

将其改回tabular原始代码，则没有错误！

问题是：如何使上述代码在 中工作longtable而不仅仅是在 中工作tabular？
答案1
tcolorbox通常\pagebreak在启动时会出现问题（除其他事项外）；在 中会忽略这个问题tabular，但在 中不会longtable。
