在Latex中将两个独立的子表创建为一个表

Question

如何在 latex 中创建下表？我不确定使用什么概念来创建此表。这两个独立的子表是否合并为一个？任何指示或建议都值得赞赏。

Answer 1

重现图片并不难；关键是要有两个t操作对齐的tabular环境。

\documentclass{article}
\usepackage{booktabs}

\begin{document}

\begin{table}[htp]
\centering

\begin{tabular}[t]{lr}
\textbf{Metric} & \textbf{Percent} \\
\toprule
\textbf{Gender} \\
Male & 54 \\
Female & 46 \\
\midrule
\textbf{Education} \\
B.S. or above & 49 \\
Some college & 39 \\
H.S. or below & 13 \\
\midrule
\textbf{Age} \\
18-29 years & 34 \\
30-49 years & 55 \\
50-64 years & 9 \\
65+ years & 1 \\
\midrule
\end{tabular}
\begin{tabular}[t]{lr}
\textbf{Metric} & \textbf{Percent} \\
\toprule
\textbf{Ethnicity} \\
Caucasian & 78 \\
African Am. & 10 \\
Asian & 1 \\
Hispanic & 7 \\
\midrule
\textbf{Smartphone} \\
\textbf{Use} \\
9+ & 10 \\
6-9 & 13 \\
3-6 & 38 \\
0-3 & 39 \\
No smartphone & $<$1 \\
\bottomrule
\end{tabular}

\caption{Whatever}

\end{table}

\end{document}

改进的版本规则更少，并且使用短破折号代替连字符。

\documentclass{article}
\usepackage{booktabs}

\begin{document}

\begin{table}[htp]
\centering

\begin{tabular}{@{}c@{}}
\toprule
\begin{tabular}[t]{@{}lr@{}}
Metric & Percent \\
\midrule
\textit{Gender} \\
Male & 54 \\
Female & 46 \\
\addlinespace
\textit{Education} \\
B.S. or above & 49 \\
Some college & 39 \\
H.S. or below & 13 \\
\addlinespace
\textit{Age} \\
18--29 years & 34 \\
30--49 years & 55 \\
50--64 years & 9 \\
65+ years & 1 \\
\end{tabular}\qquad
\begin{tabular}[t]{@{}lr@{}}
Metric & Percent \\
\midrule
\textit{Ethnicity} \\
Caucasian & 78 \\
African Am. & 10 \\
Asian & 1 \\
Hispanic & 7 \\
\addlinespace
\textit{Smartphone use} \\
9+ & 10 \\
6--9 & 13 \\
3--6 & 38 \\
0--3 & 39 \\
No smartphone & $<$1 \\
\end{tabular} \\
\bottomrule
\end{tabular}

\caption{Whatever}

\end{table}

\end{document}

一个简单的例子——下次一定要尝试展示你的努力，因为在表格内容中输入所有细节是很累人的

\documentclass[12pt,letterpaper]{article}    
\usepackage[left=20mm,top=30mm,bottom=30mm,right=20mm]{geometry}
\usepackage{booktabs} % format SI units

\begin{document}


    \begin{table}
        \centering
        \caption{Example of two independent sub-tables with booktabs package}
        \begin{tabular}{lr}
%           \toprule
            \textbf{Metric} & \textbf{Percent} \\
            \toprule
            \textbf{Gender} & \\
            1 & 2 \\
            \midrule
            \textbf{Education} & \\
            3 & 4 \\
            \bottomrule
        \end{tabular}
        \quad
        \begin{tabular}{lr}
%           \toprule
            \textbf{Metric} & \textbf{Percent} \\
            \toprule
            \textbf{Ethnicity} & \\
            5 & 6 \\
            \midrule
            \textbf{Smartphone} & \\
            7 & 8 \\
            \bottomrule
        \end{tabular}
    \end{table}
        
\end{document}
