缺少 $ 插入

tag-icon • tag-icon tables errors
缺少 $ 插入

当我使用此代码时，我在倒数第三行和第四行遇到了! Missing $ inserted.<inserted text>$ R错误! Missing $ inserted.<inserted text>$ \bottomrule。我该如何修复代码以消除这些错误？

\documentclass[letterpaper,12pt]{article}
\usepackage{tabularx,amsmath,boxedminipage,graphicx}
\usepackage[margin=1in,letterpaper]{geometry} % this shaves off default margins which are too big
\usepackage{cite}
\usepackage[final]{hyperref} % adds hyper links inside the generated pdf file
\usepackage{booktabs} % for better looking tables
\usepackage{siunitx}  % for units of measure and data in tables
\hypersetup{
    colorlinks=true,       % false: boxed links; true: colored links
    linkcolor=blue,          % color of internal links
    citecolor=blue,        % color of links to bibliography
    filecolor=magenta,      % color of file links
    urlcolor=blue         
}

\begin{document}
\begin{tabular}{
 l % left aligned column
 l % left aligned column
 *{2}{S[table-format=4.0]} % three columns with numeric data       
}
\toprule
&\textbf{Method 1} & \textbf{Method 2}\\
\midrule
Run 1 & $345 \pm 1$ & $235 \pm 3$\\
Run 2 & $465 \pm 2$ & $342 \pm 4$\\
\bottomrule
\end{tabular}
\end{document}

首先，您l在数据列前添加了两列，但据我所知，您只使用了一列。其次，让我们siunitx在列中完成所有工作S，因此不要添加美元符号。

默认情况下，siunitx不确定性以括号中的数字显示（见下面的截图）。当然，这可以更改，如您在Svend Tveskæg 的回答。

\usepackage{cite}
\usepackage[final]{hyperref} % adds hyper links inside the generated pdf file
\usepackage{booktabs} % for better looking tables
\usepackage{siunitx}  % for units of measure and data in tables
\hypersetup{
    colorlinks=true,       % false: boxed links; true: colored links
    linkcolor=blue,          % color of internal links
    citecolor=blue,        % color of links to bibliography
    filecolor=magenta,      % color of file links
    urlcolor=blue         
}

\begin{document}
\begin{tabular}{
 l % left aligned column
 *{2}{S} % three columns with numeric data       
}
\toprule
&\textbf{Method 1} & \textbf{Method 2}\\
\midrule
Run 1 & 345 \pm 1 & 235 \pm 3\\
Run 2 & 465 \pm 2 & 342 \pm 4\\
\bottomrule
\end{tabular}
\end{document}

这是一个可能的解决方案：

\documentclass{article}

\usepackage{booktabs}

\begin{document}

\begin{tabular}{lcc}
\toprule
        &\textbf{Method~1} & \textbf{Method~2}\\
\midrule
  Run~1 & $345 \pm 1$      & $235 \pm 3$      \\
  Run~2 & $465 \pm 2$      & $342 \pm 4$      \\
\bottomrule
\end{tabular}

\end{document}

输出

更新

这是使用强大的siunitx包裹：

\documentclass{article}

\usepackage{booktabs}
\usepackage{siunitx}

\begin{document}

\begin{table}
  \begin{tabular}{l *{2}{S[separate-uncertainty, table-format = 3, table-figures-uncertainty = 1]}}
   \toprule
           &\textbf{Method~1} & \textbf{Method~2}\\
   \midrule
     Run~1 & 345 \pm 1        & 235 \pm 3        \\
     Run~2 & 465 \pm 2        & 342 \pm 4        \\
   \bottomrule
  \end{tabular}
\end{table}

\end{document}
