标题中的回归表和数学的对齐问题

Question

我在回归表中的逗号对齐方面遇到了问题。由于标题中也有数学表达式，我找到的其他解决方案不起作用。这里还能把逗号排成一行吗？这是一个最小的例子（我使用 LuaLaTeX）：

\documentclass[12pt]{scrartcl}
\usepackage{amsmath}
\usepackage{mathtools}
\usepackage{unicode-math}
\usepackage{booktabs}
\usepackage{array}
\usepackage{threeparttable}
\usepackage{tabularx}

\begin{document}

\begin{table}[h]
\begin{center}
\caption{Table}
\begin{threeparttable}
\begin{tabularx}{0.7\textwidth}{@{}>{$}X<{$}>{$}c<{$}>{$}c<{$}>{$}c<{$}@{}}\\
\toprule
& (\text{minw} - p50) & (\text{minw} - p50)^2 & R^2\\
\midrule
p5 - p50 & 1{,}106^{***} & 0{,}375^{***} & 0{,}441\\
& (0{,}100) & (0{,}085) &\\
p10 - p50 & 1{,}161^{***} & 0{,}516^{***} & 0{,}575\\
& (0{,}089) & (0{,}079) &\\
\bottomrule
\end{tabularx}
\begin{tablenotes}[flushleft]
\setlength\labelsep{0pt} %So that the word „Notes“ is on the left margin
\footnotesize
\item[]Notes
\end{tablenotes}
\end{threeparttable}
\end{center}
\end{table}

\end{document}

输出如下：

Answer 1

我的主要建议是，你采用列包及其D列类型，而不是c列类型，以便将三个数据列中的数字与各自的小数点标记（逗号，不再需要用花括号括起来）对齐。第二个建议是将\caption指令里面环境并在环境启动后立即threeparttable省略该指令。第三，不要使用\\tabularxcenter 环境在环境内table；而是使用\centering命令。

  & \mc{$(\textrm{minw} - p50)^2$} 
    & \multicolumn{1}{c@{}}{$R^2$} \\
\midrule
p5 - p50  & 1,106^{***} & 0,375^{***} & 0,441 \\
          & (0,100)     & (0,085) \\
p10 - p50 & 1,161^{***} & 0,516^{***} & 0,575 \\
          & (0,089)     & (0,079) \\
\bottomrule
\end{tabularx}

\smallskip\footnotesize
\begin{tablenotes}[flushleft]
\setlength\labelsep{0pt} %So that the word „Notes“ is on the left margin

Answer 2

您可以尝试使用\mathrlap。

\documentclass[12pt]{scrartcl}
\usepackage{amsmath}
\usepackage{mathtools}
\usepackage{unicode-math}
\usepackage{booktabs}
\usepackage{array}
\usepackage{threeparttable}
\usepackage{tabularx}

\begin{document}

\begin{table}[h]
\begin{center}
\caption{Table}
\begin{threeparttable}
\begin{tabularx}{0.7\textwidth}{@{}>{$}X<{$}>{$}c<{$}>{$}c<{$}>{$}c<{$}@{}}\\
\toprule
& (\text{minw} - p50) & (\text{minw} - p50)^2 & R^2\\
\midrule
p5 - p50 & 1{,}106\mathrlap{^{***}} & 0{,}375\mathrlap{^{***}} & 0{,}441\\
& (0{,}100) & (0{,}085) &\\
p10 - p50 & 1{,}161\mathrlap{^{***}} & 0{,}516\mathrlap{^{***}} & 0{,}575\\
& (0{,}089) & (0{,}079) &\\
\bottomrule
\end{tabularx}
\begin{tablenotes}[flushleft]
\setlength\labelsep{0pt} %So that the word „Notes“ is on the left margin
\footnotesize
\item[]Notes
\end{tablenotes}
\end{threeparttable}
\end{center}
\end{table}

\end{document}
