Latex Table 合并行/列详解

1. 整体逻辑

整个table是由大小一致的单元格组成的，在这个基础上，我们通过合并单元格（行/列）的方式，实现整个table的设计：竖线用“|”，横线用“\cline“，列合并用”\multicolumn“，行合并用”\multirow“。

2. 实现步骤
从左到右逐行设计。

3. 2×2 Tabble

\usepackage{multirow}
\begin{table}[]
	\centering
	\caption{My table}
	\begin{tabular}{|c|l|}
		\hline
		1 & 2 \\ \hline
		3 & 4 \\ \hline
	\end{tabular}
\end{table}

---

\multicolumn 函数/标志符： {占用列数} {方框边界竖线|文字居左中右|方框边界竖线} {内容}

---

\usepackage{multirow}
\begin{table}[]
	\centering
	\caption{My table}
	\begin{tabular}{|c|l|}
		\hline
		1          & 2          \\ \hline
		\multicolumn{2}{|c|}{3} \\ \hline
	\end{tabular}
\end{table}

---

\multirow 函数/标志符： {占用行数} {方框边界竖线|文字居左中右|方框边界竖线} {内容}

\cline 函数/标志符：画横线

\usepackage{multirow}
\begin{table}[]
	\centering
	\caption{My table}
	\begin{tabular}{|c|l|}
		\hline
		\multirow{2}{*}{1} & 2 \\ \cline{2-2} 
		& 4 \\ \hline
	\end{tabular}
\end{table}

4. 2×3 Table

\usepackage{multirow}
\begin{table}[]
	\centering
	\caption{My table}
	\begin{tabular}{|c|l|l|}
		\hline
		1                       & 2 & 3 \\ \hline
		4                       & 5 & 6 \\ \hline
		\multicolumn{1}{|l|}{7} & 8 & 9 \\ \hline
	\end{tabular}
\end{table}

---

\multicolumn 函数/标志符： {占用列数} {方框边界竖线|文字居左中右|方框边界竖线} {内容}

\usepackage{multirow}
\begin{table}[]
	\centering
	\caption{My table}
	\begin{tabular}{|c|l|l|}
		\hline
		1                       & 2          & 3         \\ \hline
		4                       & \multicolumn{2}{l|}{5} \\ \hline
		\multicolumn{1}{|l|}{7} & 8          & 9         \\ \hline
	\end{tabular}
\end{table}

\multirow 函数/标志符： {占用行数} {方框边界竖线|文字居左中右|方框边界竖线} {内容}

\usepackage{multirow}
\begin{table}[]
	\centering
	\caption{My table}
	\begin{tabular}{|c|l|l|}
		\hline
		1                       & 2                  & 3 \\ \hline
		4                       & \multirow{2}{*}{5} & 6 \\ \cline{1-1} \cline{3-3} 
		\multicolumn{1}{|l|}{7} &                    & 9 \\ \hline
	\end{tabular}
\end{table}

5. A sample

\usepackage{multirow}
\begin{table}[]
	\centering
	\caption{A transcript sample}
	\begin{tabular}{c|l|l|l}
		\hline
		\multirow{2}{*}{Subject}    & \multicolumn{2}{c|}{Science} & Extracurricular             \\ \cline{2-4} 
		& Math        & English        & \multicolumn{1}{l}{Others} \\ \hline
		\multicolumn{1}{l|}{Score} & 95          & 93             & 90                          \\ \hline
	\end{tabular}
\end{table}
