Shortunderstack 中的数学模式错误

Question

我在 Overleaf 中遇到了一些类似的红点错误，但它仍然可以顺利编译。缩小问题范围后，我发现这是因为使用了数学模式Shortunderstack。
我该如何解决这个问题？以下是错误：

unclosed \begin{adjustbox} found at \end{array}
unclosed \begin{adjustbox} found at \end{table}
unexpected \end{array} after $
unexpected \end{array} after \begin{adjustbox}
unclosed $ found at \end{table}
unclosed open group { found at $
unexpected $ after open group {
unexpected $ after \begin{array}
unclosed $ found at \end{array}

\documentclass[journal]{IEEEtran}
\usepackage{array}
\usepackage{mathtools}
\usepackage{booktabs,capt-of}
\usepackage[export]{adjustbox}  
\usepackage[usestackEOL]{stackengine}


\begin{document}

 \begin{table}[!t]
      \centering
      \caption{A table}
      \label{tab:table 1}
    \begin{adjustbox}{max width=\linewidth}
    $\setlength{\arraycolsep}{1pt}
    \begin{array}{cc@{}cccccccl @{\quad}l }
    \toprule
    \textbf{No} & \multicolumn{9}{c}{\textbf{List}} & \multicolumn{1}{c}{\textbf{Note}} \\
    \midrule
    1 & ( & x_1, & x_2, & x_3, & x_1, & x_5, & x_6, & x_7 & ) & \Shortunderstack[l]{This is an example \\ of two line text}\\
    \addlinespace
    2 & ( & y_1, & y_2, & y_3, & y_4, & y_5, & y_6, & y_7 & ) & \Shortunderstack[l]{Math expression error $x_1+x_2$ } \\
    \bottomrule
    \end{array}$
    \end{adjustbox}
    \end{table}
%
\end{document}

Answer 1

除了通知 Overleaf 的工作人员之外，你对此没有其他办法。

另一方面，adjustbox和\Shortunderstack是不需要的。

\documentclass[journal]{IEEEtran}
\usepackage{array}
\usepackage{mathtools}
\usepackage{booktabs}

\usepackage{lipsum} % for mock text

\begin{document}

\lipsum[1-5]

\begin{table}[t]
\centering

\caption{A table}
\label{tab:table 1}

% local command
\newcommand{\stack}[1]{\begin{tabular}[t]{@{}l@{}}#1\end{tabular}}

$\setlength{\arraycolsep}{1pt}
\begin{array}{@{}cc@{}cccccccl @{\enspace}l@{}}
\toprule
\textbf{No} & \multicolumn{9}{c}{\textbf{List}} & \multicolumn{1}{c}{\textbf{Note}} \\
\midrule
1 & ( & x_1, & x_2, & x_3, & x_1, & x_5, & x_6, & x_7 & ) & 
  \stack{This is an example \\ of two line text}\\
\addlinespace
2 & ( & y_1, & y_2, & y_3, & y_4, & y_5, & y_6, & y_7 & ) &
  \stack{Math expression error \\ $x_1+x_2$ } \\
\bottomrule
\end{array}$

\end{table}

\lipsum

\end{document}
