当我编译以下代码时，我发现在 ax、bx、cx 和 dx 下的通用寄存器的多列中出现了一行奇怪的行。
\documentclass[11pt,a5paper,footinclude=true,headinclude=true]{scrbook} % KOMA-Script book
\usepackage[T2A]{fontenc}
\usepackage{multirow}
\begin{document}
\begin{center}
\begin{tabular}{|c|c|c|c|}
\hline
Type & \multicolumn{2}{c|}{Register} & Purpose \\\hline\hline
\multirow{16}{*}{General Purpose} & \multirow{2}{*}{ax} & ah & \multirow{2}{*}{Arithmetic} \\

我在多列/行中做错了什么吗
答案1
下面两列sp应该di替换为：
\multicolumn{2}{c|}{}
去掉垂直线。
完整示例：
\documentclass[11pt,a5paper,footinclude=true,headinclude=true]{scrbook} % KOMA-Script book
\usepackage{multirow}
\begin{document}
\begin{center}
\begin{tabular}{|c|c|c|c|}
\hline
Type & \multicolumn{2}{c|}{Register} & Purpose \\\hline\hline
\multirow{16}{*}{General Purpose} & \multirow{2}{*}{ax} & ah & \multirow{2}{*}{Arithmetic} \\
\cline{3-3}
& & al & \\
\cline{2-4}
& \multirow{2}{*}{bx} & bh & \multirow{2}{*}{Base} \\
\cline{3-3}
& & bl & \\
\cline{2-4}
& \multirow{2}{*}{cx} & ch & \multirow{2}{*}{Counter} \\
\cline{3-3}
& & cl & \\
\cline{2-4}
& \multirow{2}{*}{dx} & dh & \multirow{2}{*}{Data} \\
\cline{3-3}
& & dl & \\
\cline{2-4}
& \multicolumn{2}{c|}{\multirow{2}{*}{sp}} & \multirow{2}{*}{Stack Pointer} \\
& \multicolumn{2}{c|}{} & \\
\cline{2-4}
& \multicolumn{2}{c|}{\multirow{2}{*}{bp}} & \multirow{2}{*}{Base Pointer} \\
& \multicolumn{2}{c|}{} & \\
\cline{2-4}
& \multicolumn{2}{c|}{\multirow{2}{*}{si}} & \multirow{2}{*}{Source Index} \\
& \multicolumn{2}{c|}{} & \\
\cline{2-4}
& \multicolumn{2}{c|}{\multirow{2}{*}{di}} & \multirow{2}{*}{Destination Index} \\
& \multicolumn{2}{c|}{} & \\
\hline
\multirow{6}{*}{Segment} & \multicolumn{2}{c|}{ss} & Stack Segment \\
\cline{2-4}
& \multicolumn{2}{c|}{cs} & Code Segment \\
\cline{2-4}
& \multicolumn{2}{c|}{ds} & Data Segment \\
\cline{2-4}
& \multicolumn{2}{c|}{es} & Extra Segment \\
\cline{2-4}
& \multicolumn{2}{c|}{fs} & Extra Segment \\
\cline{2-4}
& \multicolumn{2}{c|}{gs} & Extra Segment \\
\hline
\end{tabular}
\end{center}
\end{document}
还有一个没有垂直线和较少水平线的版本，带有包装规则booktabs：
\documentclass{article}
\usepackage{booktabs}
\begin{document}
\begin{center}
\begin{tabular}{llll}
\toprule
Type & \multicolumn{2}{l}{Register} & Purpose \\
\midrule
General Purpose & ax & ah & Arithmetic \\
& & al & \\
\addlinespace % \cmidrule{2-4}
& bx & bh & Base \\
& & bl & \\
\addlinespace
& cx & ch & Counter \\
& & cl & \\
\addlinespace
& dx & dh & Data \\
& & dl & \\
\cmidrule{2-4}
& \multicolumn{2}{l}{sp} & Stack Pointer \\
& \multicolumn{2}{l}{bp} & Base Pointer \\
& \multicolumn{2}{l}{si} & Source Index \\
& \multicolumn{2}{l}{di} & Destination Index \\
\midrule
Segment & \multicolumn{2}{l}{ss} & Stack Segment \\
& \multicolumn{2}{l}{cs} & Code Segment \\
& \multicolumn{2}{l}{ds} & Data Segment \\
& \multicolumn{2}{l}{es} & Extra Segment \\
& \multicolumn{2}{l}{fs} & Extra Segment \\
& \multicolumn{2}{l}{gs} & Extra Segment \\
\bottomrule
\end{tabular}
\end{center}
\end{document}
