我怎样才能重新创建该表？

Question

我想使用与该图中使用的相同类型的设置，但是我似乎无法找到如何以一种在编译时不会出错的方式添加多行。

Answer 1

实际上没有太多的事情要做：计算要跨越的行数。

\documentclass{article}
\usepackage{geometry}
\usepackage{newpxtext,newpxmath}

\usepackage{siunitx}
\usepackage{booktabs}
\usepackage{multirow}

\DeclareSIUnit{\voltac}{VAC}
\DeclareSIUnit{\kilogrammetre}{kgm}

\begin{document}

\begin{table}[htp]
\centering

\begin{tabular}{ccc}
\toprule
\multirow{9}{*}{PMSG} &
  Rated Power & \qty{2}{\mega\watt} \\
& Rated rotate speed & \qty{650}{rpm} \\
& Rated Voltage & \qty{690}{\voltac} \\
& Rated current & \qty{1673.5}{\ampere} \\
& Number of pole pairs & 4 \\
& Resistance ($R_s$) & \qty{0.0024}{\ohm} \\
& Inductances ($L_d=L_q$) & \qty{0.3552}{\milli\henry} (line-phase) \\
& Magnetic flux ($\Psi_m$) & \qty{0.666}{\weber} \\
& Inertia (J) & \qty{2}{\kilogrammetre^2} \\ 
\midrule
\multirow{3}{*}{Grid side Filter} &
  Inductance & \qty{1.6}{\milli\henry} \\
& Resistance & \qty{0.01}{\ohm} \\
& Rated charge/discharge currents & \qty{1500}{\ampere} \\
\midrule
\end{tabular}

\end{table}

\end{document}

完全的。

另一方面，这样的表格很难读懂。这里有一个不同的提议。

\documentclass{article}
\usepackage{geometry}
\usepackage{newpxtext,newpxmath}

\usepackage{siunitx}
\usepackage{booktabs}

\DeclareSIUnit{\voltac}{VAC}
\DeclareSIUnit{\voltrms}{Vrms}

\begin{document}

\begin{table}[htp]
