我正在尝试制作一个与此类似的表格：
...失败了。这是我的代码：
\documentclass[a4paper]{article}
\usepackage[english]{babel}
\usepackage[utf8x]{inputenc}
\usepackage{graphicx}
\usepackage{wrapfig}
\usepackage{lipsum}
\usepackage{multirow}
\begin{document}
\begin{table}[h]
\caption{This is a caption}
\centering % centering table
\begin{tabular}{|l| p{5cm} | p{5cm} | c|}
\hline
Domain & Sub-domain & Use case &Suitable \\
\hline % inserts single-line
Metering & Water, Electricity or Gas distribution & Collect daily or bi- hourly water, electricity and gas usage data. & Yes \\
\hline
\multirow{9}{2cm}{Infrastructure networks} & Water \& Gas transportation & Water and Gas infrastructure network surveillance (alarm,
metering parameters) & Yes\\
& Power Grid & Electricity transport status monitoring and
command/control & Yes \\
& Power Grid & Command and control & Yes \\
& Traffic monitoring & Traffic light functionality monitoring, traffic level monitoring, & Yes \\
& Traffic shaping & emergency gate status control, traffic lights control & Potentially \\
\hline
\multirow{7}{3cm}{Environmental \& Smart City} & Pipelines & Collect data on Metrics (temperature, pressure), alarms, leakage, vibration & yes \\
& Waste and Drains management & Collect data on levels & yes \\
& Atmospheric Noise-Pollution monitoring & Collect data on humidity, noise, temperature,$CO_2$,CO, etc. & yes \\
& Public Lighting Monitoring & Bulb monitoring & yes \\
& Parking management & Availability monitoring & yes \\
\hline
\end{tabular}
\end{table}
\end{document}
这就产生了：
它非常接近我想要的，但我找不到让水平线出现在应有位置的方法。 \hline 也会创建跨越第一行的线。
任何帮助将非常感激。
答案1
就像@HeikoOberdiek 所说的那样，\cline 就是答案。具体来说，对于我的需求，
\multirow{9}{2cm}{Infrastructure networks} & Water \& Gas transportation & Water and Gas infrastructure network surveillance (alarm,
metering parameters) & Yes\\
\cline{2-4}
& Power Grid & Electricity transport status monitoring and
command/control & Yes \\
\cline{2-4}
& Power Grid & Command and control & Yes \\
\cline{2-4}
& Traffic monitoring & Traffic light functionality monitoring, traffic level monitoring, & Yes \\
\cline{2-4}
& Traffic shaping & emergency gate status control, traffic lights control & Potentially \\
\hline
正是我想要的。谢谢
