Latex表格：如何在多行单元格中删除水平线？

latextabular
3

我对Latex非常陌生，正在尝试创建一个跨多行的表格。我要解决的问题是移除放置在跨行单元格上的水平线。这里链接了目前的情况截图：

我的代码如下。图片中用方框标出的区域表示跨行单元格有水平线覆盖。我尝试使用cline{}命令来移除水平线，但结果要么移除了不止一条线，要么根本没有移除任何线。我不认为我完全理解如何使用该命令。当未被注释时，我已将显示我所说内容的两个cline命令注释掉。

看看新的tabularray包。这将为您提供更好的结果，整齐地分布行，并自动处理水平线：

\documentclass[12pt,a4paper]{article}

\usepackage[margin=1in]{geometry}

\usepackage{tabularray}

\begin{document}

\noindent
\begin{tblr}{
  colspec={ c c c X},
  vlines,
  hlines,
  vspan=even
}
    H & 160.01 – 320 N·s & 36.01 – 71.9 lbf·s & \SetCell[r=2]{} \textbf{High Power | Level 1} \newline Level 1 Certification required for purchase. Certification available through Tripoli or NAR.
    Under 125g propellant is Federal Aviation Administration exempt.\\
    I & 320.01 – 640 N·s & 71.9 – 144 lbf·s & \\
\end{tblr}

\end{document}

在此输入图片描述

（您可能需要查看 siunitx 包以获得数字和单位的适当间距...）

您可以通过用 \cline{1-3} 替换一些 \hline 来进行修复。更准确地说，当 multirow 跨越了 n 行时，在它之后必须进行 n-1 次此替换。

此外，使用此标题时，\begin{tabular}{c|c|c|c{3.5cm}} 和 \multirow{3}{150}{} 会出现错误。
