Tabularx：调整列名称以适应条目

Question

我有以下 MWE：

\documentclass[12pt, a4paper]{article}
\usepackage[english]{babel}


\usepackage{amsmath}
\usepackage{amssymb} 
\usepackage{amsthm}

\usepackage{tabularx}
\usepackage{array}
\usepackage{caption}

\usepackage{booktabs, siunitx}
\usepackage{dcolumn}
\NewExpandableDocumentCommand\mcc{O{1}m}
    {\multicolumn{#1}{c}{#2}}

\begin{document}    

\begin{table}[h!]
\begin{scriptsize}
\centering
\caption{Caption}
\setlength{\tabcolsep}{3pt}
\renewcommand{\arraystretch}{1.10}
\begin{tabular*}{\linewidth}{l @{\extracolsep{\fill}}*{3}{D{.}{.}{6}}}
\toprule
& \mcc[1]{Col A}
& \mcc[1]{Col B} 
& \mcc[1]{Col C} \\
\midrule

\multicolumn{4}{l}{\textbf{Panel A: This is model 1}}\\
\midrule
ABC  &-1.23^{***}  &-6.12   &-4.32^{*}\\
     &(-9.01)      &(-3.32) &(6.12)
\\
DEF  &-4.12        &7.01    &-0.71\\
     &(1.54)       &(0.02)  &(-1.52)

\\
\multicolumn{4}{l}{\textbf{Panel B: This is model 2 that has a longer name than model 1}}\\
\midrule
ABC  &-0.64^*   &-0.52      &-6.01^{**}\\
     &(-1.86)   &(-7.13)    &(-9.43)   \\
DEF  &-0.23     &0.01       &-6.71  \\
     &(-0.43)   &(3.12)     &(-3.52)\\
\bottomrule
\end{tabular*} 
\end{scriptsize}
\end{table}


\end{document}

我对此表的唯一问题是列标签与条目不对齐，请参见下面的标记：

我注意到这是因为标题Panel B: This is model 2 that has a longer name than model 1太长。有没有办法保留标题原样，但将条目与列名对齐Col C？

Answer 1

tabularx这与您使用的标准无关tabular*。

我个人会tabular在这里使用，因为强制表格全宽只会使列之间的距离更大，表格更难阅读（对于任何表格来说，这几乎都是这种情况）

但如果你确实希望表格占满整个宽度，你可以隐藏跨越条目的宽度，这样宽度就会在每列之间平均分配

和tabularx：

\documentclass[12pt, a4paper]{article}

\usepackage{booktabs, tabularx}
\NewExpandableDocumentCommand\mcx{O{1}m}

\NewExpandableDocumentCommand\mclbf{O{1}m}
    {\multicolumn{#1}{>{\bfseries}l}{#2}}
\usepackage{caption}

\usepackage{siunitx}

\begin{tabularx}{\linewidth}{ l *{3}{S} }
