我是 Latex 的新用户，这是我第一次尝试为我的论文构建表格。我希望表格看起来像这样：
在网上进行了一些研究后，我得到了以下代码（忽略 Latex 代码和 Word 文档之间的列标题差异）
\begin{table}[htbp]
\caption{Minimum Requirements for Automatic Readmission into the Commerce Faculty}
\centering
\begin{tabular}{lrrrr}
\toprule
\multicolumn{2}{c}{{BCom} &
\multicolumn{2}{c}{B.Bus.Sci} \\
\cmidrule{2-3} \cmidrule{4-5} &
Number of courses required to pass & Cumulative Total of Courses && Number of courses & Cumulative Total of Courses
\midrule
First year & 4 & 8 & 4 & 18 \\
\bottomrule
\end{tabular}
\label{table:mr}
\end{table}
它根本不起作用！
答案1
更好的版本：
\documentclass{article}
\usepackage{booktabs}
\usepackage[margin=1in]{geometry}
\usepackage{array}
\newcolumntype{L}[1]{>{\raggedright\arraybackslash}p{#1}}
\begin{document}
\begin{table}[htbp]
\caption{Minimum Requirements for Automatic Readmission into the Commerce Faculty}
\centering
\begin{tabular}{@{}p{0.12\textwidth}*{4}{L{\dimexpr0.22\textwidth-2\tabcolsep\relax}}@{}}
\toprule
& \multicolumn{2}{c}{BCom} &
\multicolumn{2}{c}{B.Bus.Sci} \\
\cmidrule(r{4pt}){2-3} \cmidrule(l){4-5}
& Number of courses required to pass & Cumulative Total of Courses & Number of courses & Cumulative Total of Courses\\
\midrule
First year & 4 & 8 & 4 & 18 \\
\bottomrule
\end{tabular}
\label{table:mr}
\end{table}
\end{document}
为什么你的代码无法编译？
你错过
&了\multicolumn{2}{c}{{BCom} & \multicolumn{2}{c}{B.Bus.Sci} \\将第一个条目放入第一列。
&&你有Number of courses required to pass & Cumulative Total of Courses && Number of courses & Cumulative Total of Courses应该是
&，你应该&在行首放一个。而在这一行的末尾，你刚好\\在之前漏掉了一个\cmidrule。
现在修改
array在纠正了以上所有内容之后，我在包的帮助下引入了一种新的列类型：
\usepackage{array}
\newcolumntype{L}[1]{>{\raggedright\arraybackslash}p{#1}}
\raggedright添加是为了避免难看的对齐效果，因为列可能很窄，单词的长度也可能不同。这也能解决坏框的问题。
我已经使用L宽度为
\dimexpr0.22\textwidth-2\tabcolsep\relax
通过
*{4}{L{\dimexpr0.22\textwidth-2\tabcolsep\relax}}
而不是重复。
附注：可以将eft 或ight\cmidrule缩写为lr
\cmidrule(r{4pt}){2-3}
这{4pt}是我们缩短的量。可以像 一样省略\cmidrule(r){4-5}。
答案2
除了使用该booktabs包（以获得美观的、即间距适当的水平线）之外，我还建议您使用该tabularx包来简化获取四个等宽列的工作。
\documentclass{article}
\usepackage{booktabs,tabularx}
\usepackage[margin=1in]{geometry} % set margins to meet your document's needs
\newcolumntype{Y}{>{\raggedright\arraybackslash}X}
% use ragged-right, not fully-justified, look in narrow columns
\begin{document}
\begin{table}[t]
\caption{Minimum Requirements for Automatic Readmission
into the Commerce Faculty} \label{table:mr}
%\centering % not needed, since table is as wide as text block
\begin{tabularx}{\textwidth}{@{}lYYYY@{}}
\toprule
&\multicolumn{2}{c}{\bfseries BCom}
&\multicolumn{2}{c}{\bfseries B.Bus Sci} \\
\cmidrule(lr){2-3} \cmidrule(l){4-5}
&Number of courses required to pass
&Cumulative Total of Courses
& Number of courses
& Cumulative Total of Courses\\
\midrule
First year & 4 & 8 & 4 & 18 \\
\bottomrule
\end{tabularx}
\end{table}
\end{document}
附录：顺便说一句，您在帖子中展示的表格的外观可以不是使用该包的命令即可实现。如果您确实需要所有这些垂直线和水平线，则booktabs不应使用命令\toprule、\bottomrule和。相反，只需使用 basic-LaTeX指令即可。（当然，您仍然可以使用该包来简化表格第 2 列至第 5 列等宽列的创建。）\midrule\cmidrule\hlinetabularx
这些修改将导致表格如下所示。我希望你会同意“书本标签外观”——没有垂直线，总体上水平线较少，并且间隔适当——比所谓的“电子表格外观”要好得多。
\documentclass{article}
\usepackage{tabularx}
\usepackage[margin=1in]{geometry} % choose margin as needed
\newcolumntype{Y}{>{\raggedright\arraybackslash}X}
\begin{document}
\begin{table}[h!]
\caption{Minimum Requirements for Automatic Readmission
into the Commerce Faculty} \label{table:mr}
\begin{tabularx}{\textwidth}{|l|Y|Y|Y|Y|}
\hline
&\multicolumn{2}{c|}{\bfseries B. Com}
&\multicolumn{2}{c|}{\bfseries B. Bus. Sci} \\ \hline
& Number of courses required to pass
& Cumulative Total of Courses
& Number of courses required to pass
& Cumulative Total of Courses \\ \hline
First Year & 4 & 8 & 4 & 18 \\ \hline
Second Year & 10 & 16 & 11 & 16 \\ \hline
Third Year & 18 & 24 & 20 & 25 \\ \hline
\end{tabularx}
\end{table}
\end{document}

看看下面的内容：
