tabularx 表中的多个列的宽度自动相等吗？

Question

以下代码生成了我想要的表格类型，但它确实将几乎所有空间都分配给了第一个单元格。我希望它们均匀分割，而不提供确切的单元格宽度，因为每次我有不同数量的列时我都必须重新计算。

\documentclass[a4paper]{article}

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[ngerman,english]{babel}
\usepackage{tabularx}  % for 'tabularx' environment and 'X' column type
\usepackage{ragged2e}  % for '\RaggedRight' macro (allows hyphenation)
\newcolumntype{Y}{>{\RaggedRight\arraybackslash}X} 
\usepackage{booktabs}  % for \toprule, \midrule, and \bottomrule macros 

\begin{document}
\begin{table}
\begin{tabularx}{\textwidth}{@{} Y c c c @{}} % use 'Y' for first column
\toprule
1 & 2 & 3 \\
\midrule
1 & \begin{tabular}{l} 2  \\ 3\end{tabular} & \begin{tabular}{l} 1 \\ 2\end{tabular} \\
1 & \begin{tabular}{l} 2  \\ 3\end{tabular} & \begin{tabular}{l} 1 \\ 2\end{tabular} \\
1 & \begin{tabular}{l} 2  \\ 3\end{tabular} & \begin{tabular}{l} 1 \\ 2\end{tabular} \\
1 & \begin{tabular}{l} 2  \\ 3\end{tabular} & \begin{tabular}{l} 1 \\ 2\end{tabular} \\
\bottomrule
\end{tabularx}
\caption{Nonlinear Model Results} 
\label{table:nonlin}
\end{table}
\end{document}

Answer 1

您必须X在希望尽可能宽的每一列上使用类型列。可用空间在这些列之间平均分配。

因此，对于居中X类型的列，您可以定义\newcolumntype{Z}{>{\centering\arraybackslash}X}。我还为内部\begin{tabular}...\end{tabular}构造定义了一个快捷方式宏。

\documentclass[a4paper]{article}

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[ngerman,english]{babel}
\usepackage{tabularx}  % for 'tabularx' environment and 'X' column type
\usepackage{ragged2e}  % for '\RaggedRight' macro (allows hyphenation)
\newcolumntype{Y}{>{\RaggedRight\arraybackslash}X} 
\newcolumntype{Z}{>{\centering\arraybackslash}X} 
\usepackage{booktabs}  % for \toprule, \midrule, and \bottomrule macros 
\newcommand\CELL[2][l]{\begin{tabular}{@{}#1@{}}#2\end{tabular}}

\begin{document}
\begin{table}
\begin{tabularx}{\textwidth}{@{} Y Z Z Z @{}} % use 'Y' for first column
\toprule
1 & 2 & 3 \\
\midrule
1 & \CELL{2\\3} & \CELL{1\\2} \\
1 & \CELL{2\\3} & \CELL{1\\2} \\
1 & \CELL{2\\3} & \CELL{1\\2} \\
1 & \CELL{2\\3} & \CELL{1\\2} \\
\bottomrule
\end{tabularx}
\caption{Nonlinear Model Results} 
\label{table:nonlin}
\end{table}
\end{document}

为了生成图像，我添加了垂直规则以显示它们都具有相同的宽度。

Answer 2

\documentclass[a4paper]{article}
\usepackage{caption}
\usepackage{tabularx}
\usepackage{ragged2e}
\renewcommand\tabularxcolumn[1]{m{#1}}
\newcolumntype{Y}{>{\RaggedRight}X} 
\newcolumntype{Z}{>{\Centering}X} 
\usepackage{booktabs}  
\let\CELL\shortstack

\begin{document}
\begin{table}
\caption{Nonlinear Model Results} \label{table:nonlin}
\begin{tabularx}{\textwidth}{@{} Y Z Z @{}}\toprule
    1 & 2 & 3 \\\midrule
    1 & \CELL{2\\3} & \CELL{1\\2} \\
    1 & \CELL{2\\3} & \CELL{1\\2} \\
    1 & \CELL{2\\3} & \CELL{1\\2} \\
    1 & \CELL{2\\3} & \CELL{1\\2} \\\bottomrule
\end{tabularx}
\end{table}

\end{document}

表格的标题应位于表格上方：
