Latex 三线表制作，合并单元格， 加粗， 旋转等基于Overleaf

这些统称为Latex的浮动体参数，用于控制当前对象（图、表）等在页面上的相对位置。

一般情况下，使用[!htbp]表示浮动体按照当前位置、页面顶部、页面底端和另一页搜寻最优位置。

 经典三线格无需依赖任何外置包

\documentclass{article}

\begin{document}

\begin{table}[!htbp] \caption{\textbf{Classical table}}%title \centering \begin{tabular}{cccc}% four columns \hline %begin the first line T 1 & T 2 & T 3 & T 4 \\ \hline %begin the second line D1 & D2 & D3 & D4 \\ D5 & D6 & D7 & D8 \\ \hline %begin the third line \end{tabular} \end{table}   \end{document}

 效果图如下：

Latex 代码段：加粗主要导入的包有 \usepackage{booktabs}, 其中第一条线和最后一条线设置为2pt的线宽。

\documentclass{article} \usepackage{booktabs} % provide \toprule, \midrule, bottomrule

\begin{document}

\begin{table}[!htbp] \caption{\textbf{Classical table}}%title \centering \begin{tabular}{cccc}% four columns \toprule[2pt] %change the first line to \toprule T 1 & T 2 & T 3 & T 4 \\ \midrule %change the second line to midrule D1 & D2 & D3 & D4 \\ D5 & D6 & D7 & D8 \\ \bottomrule[2pt] %change the third line to bottomrule \end{tabular} \end{table}

\end{document}

使用四线表的方式比较简单，即多加一行\midrule就能解决：

\documentclass{article} \usepackage{booktabs} % provide \toprule, \midrule, bottomrule

\begin{document} \begin{table}[!htbp] \caption{\textbf{Classical table}}%title \centering \begin{tabular}{cccc}% four columns \toprule[2pt] %change the first line to \toprule T 1 & T 2 & T 3 & T 4 \\ \midrule %change the second line to midrule D1 & D2 & D3 & D4 \\ D5 & D6 & D7 & D8 \\ \midrule D9 & D10 & D11 & D12 \\ \bottomrule[2pt] %change the third line to bottomrule \end{tabular} \end{table}

\end{document}

使用 \multicolumn合并行两列

 \documentclass{article} \usepackage{booktabs} % provide \toprule, \midrule, bottomrule

\begin{document} \begin{table}[!htbp] \caption{\textbf{Classical table}}%title \centering \begin{tabular}{cccc}% four columns \toprule[2pt] %change the first line to \toprule \multicolumn{2}{c}{T1}  & \multicolumn{2}{c}{T2} \\ \midrule %change the second line to midrule D1 & D2 & D3 & D4 \\ D5 & D6 & D7 & D8 \\ \bottomrule[2pt] %change the third line to bottomrule \end{tabular} \end{table}

\end{document}

注意，这里要修改一下表格整体的列数

\documentclass{article} \usepackage{booktabs} % provide \toprule, \midrule, bottomrule

\begin{document} \begin{table}[!htbp] \caption{\textbf{Classical table}}%title \centering \begin{tabular}{ccccc}% four columns \toprule[2pt] %change the first line to \toprule \multicolumn{2}{c}{T1}  & \multicolumn{3}{c}{T2} \\ \midrule %change the second line to midrule D1 & D2 & D3 & D4 & D9\\ D5 & D6 & D7 & D8 & D10\\ \bottomrule[2pt] %change the third line to bottomrule \end{tabular} \end{table}

\end{document}

注意，这里需要导入\usepackage{multirow}，便于后续的cline（插入不同长短的线）以及合并行操作。

例如\cline{2-5}，代表了该位置从第二列到第五列画线

 \documentclass{article} \usepackage{booktabs} % provide \toprule, \midrule, bottomrule \usepackage{multirow}

\begin{document} \begin{table}[!htbp] \caption{\textbf{Classical table}}%title \centering \begin{tabular}{ccccc}% four columns \toprule[2pt] %change the first line to \toprule \multirow{2}*{T0} & \multicolumn{2}{c}{T1}  & \multicolumn{2}{c}{T2} \\ & D2 & D3 & D4 & D9\\ \cline{2-5} %change the second line to midrule D5 & D6 & D7 & D8 & D10\\ D11 & D12 & D13 & D14 & D15\\ \bottomrule[2pt] %change the third line to bottomrule \end{tabular} \end{table}

\end{document}

使用\renewcommand\arraystretch{}调整行间距

\documentclass{article} \usepackage{booktabs} % provide \toprule, \midrule, bottomrule \usepackage{multirow}  

\begin{document} \begin{table}[!htbp] \renewcommand\arraystretch{2.0} \caption{\textbf{Classical table}}%title \centering \begin{tabular}{ccccc}% four columns \toprule[2pt] %change the first line to \toprule \multirow{2}*{T0} & \multicolumn{2}{c}{T1}  & \multicolumn{2}{c}{T2} \\ & D2 & D3 & D4 & D9\\ \cline{2-5} %change the second line to midrule D5 & D6 & D7 & D8 & D10\\ D11 & D12 & D13 & D14 & D15\\ \bottomrule[2pt] %change the third line to bottomrule \end{tabular} \end{table}

\end{document}

写论文时为了突出方法的有点，可以从大量的数据中表出最大值或者第二大值，使得表格的阅读性更佳。

\documentclass{article} \usepackage{booktabs} % provide \toprule, \midrule, bottomrule \usepackage{multirow}  

\begin{document} \begin{table}[!htbp] \renewcommand\arraystretch{2.0} \caption{\textbf{Classical table}}%title \centering \begin{tabular}{ccccc}% four columns \toprule[2pt] %change the first line to \toprule \multirow{2}*{T0} & \multicolumn{2}{c}{T1}  & \multicolumn{2}{c}{T2} \\ & D2 & D3 & D4 & D9\\ \cline{2-5} %change the second line to midrule \underline{D5} & \underline{D6} & D7 & D8 & D10\\ \textbf{D11} & \textbf{D12} & D13 & D14 & D15\\ \bottomrule[2pt] %change the third line to bottomrule \end{tabular} \end{table}

\end{document}

表格过大时需要进行翻转操作，旋转90°。使用sidewaystable代替table环境。

 \documentclass{article} \usepackage{booktabs} % provide \toprule, \midrule, bottomrule \usepackage{multirow} \usepackage[figuresright]{rotating}  

\begin{document} \begin{sidewaystable}[!htbp] \renewcommand\arraystretch{2.0} \caption{\textbf{Classical table}}%title \centering \begin{tabular}{ccccc}% four columns \toprule[2pt] %change the first line to \toprule \multirow{2}*{T0} & \multicolumn{2}{c}{T1}  & \multicolumn{2}{c}{T2} \\ & D2 & D3 & D4 & D9\\ \cline{2-5} %change the second line to midrule \underline{D5} & \underline{D6} & D7 & D8 & D10\\ \textbf{D11} & \textbf{D12} & D13 & D14 & D15\\ \bottomrule[2pt] %change the third line to bottomrule \end{tabular} \end{sidewaystable}

\end{document}
