如何水平對齊X型列之間的行？

Question

我有一張帶有短標題和長標題的表格。我正在使用包X中的列類型tabularx。標題與頂部對齊，如何將標題水平居中對齊？

\documentclass[12pt,a4paper]{article}
\usepackage{tabularx}
\usepackage{booktabs}
\usepackage{array}

\begin{document}

\begin{table}[htb]
\centering
\caption{My caption}
\label{my-label}
\begin{tabularx}{\linewidth}{*2{>{\centering\arraybackslash}X}}
\toprule
\textbf{Short heading\newline(units)} &
\textbf{This is a long long, very very long heading\newline(units)}\\%
\midrule
416,09 & 194,30 \\
\bottomrule
\end{tabularx}
\end{table}

\end{document}

Answer 1

假設您想要實現水平和垂直居中的條目，您可以使用以下X類型列的重新定義。通常它們源自於p頂部對齊的類型列。我們\renewcommand{\tabularxcolumn}[1]{m{#1}}可以更改這一點，以便x類型列派生自垂直居中的m類型列。

\documentclass[12pt,a4paper]{article}
\usepackage{tabularx}
\usepackage{booktabs}
\usepackage{array}

\renewcommand{\tabularxcolumn}[1]{m{#1}}

\begin{document}

\begin{table}[htb]
\centering
\caption{My caption}
\label{my-label}
\begin{tabularx}{\linewidth}{*2{>{\centering\arraybackslash}X}}
\toprule
\textbf{Short heading\newline(units)} &
\textbf{This is a long long, very very long heading\newline(units)}\\%
\midrule
416,09 & 194,30 \\
\bottomrule
\end{tabularx}
\end{table}

\end{document}

如果您想X在整個文件中更頻繁地使用水平和垂直居中類型的列，您還可以添加\newcolumntype{Y}{>{\centering\arraybackslash}X}到序言中並使用\begin{tabularx}{\linewidth}{*2{Y}}.

如果您希望保留頂部對齊X類型列的原始定義並擁有單獨的派生和垂直居中的列類型，您可能需要查看將 tabularx X 列複製為新的垂直居中列

如果您只想變更單一資料表的垂直對齊方式，則可以使用下列X類型列的本機重新定義。這裡我在相應的表的\renewcommand{\tabularxcolumn}[1]{m{#1}}後面添加了。\begin{table}

\documentclass[12pt,a4paper]{article}
\usepackage{tabularx}
\usepackage{booktabs}
\usepackage{array}


\begin{document}

\begin{table}[htb]
\centering

\label{my-label}
\begin{tabularx}{\linewidth}{*2{>{\centering\arraybackslash}X}}
\toprule
\textbf{Short heading\newline(units)} &
\textbf{This is a long long, very very long heading\newline(units)}\\%
\midrule
416,09 & 194,30 \\
\bottomrule
\end{tabularx}
\end{table}

\begin{table}[htb]
\renewcommand{\tabularxcolumn}[1]{m{#1}}
\centering
\caption{My caption}
\label{my-label}
\begin{tabularx}{\linewidth}{*2{>{\centering\arraybackslash}X}}
\toprule
\textbf{Short heading\newline(units)} &
\textbf{This is a long long, very very long heading\newline(units)}\\%
\midrule
416,09 & 194,30 \\
\bottomrule
\end{tabularx}
\end{table}
