Latex 表格：如何刪除多行單元格中的水平線？

Question

我對 Latex 非常陌生，並且正在嘗試創建一個包含跨多行的單元格的表格。 我要解決的問題是刪除放置在多行單元格上的水平線。 到目前為止我所擁有的圖片鏈接在這里

Latex_table_screenshot

我的代碼如下。 圖片中的方框區域表示有線條越過它們的多行單元格。 我曾嘗試使用 cline{} 命令刪除水平線，但最終會刪除多條線或根本不刪除。 我認為我不完全了解如何使用該命令。 我注釋掉了兩個 cline 命令，它們在未注釋時顯示了我在說什么。

Answer 1

您可以通過用\cline{1-3}替換一些\hline來修復。 更准確地說，在multirow跨越n行的情況下，您必須在它之后進行n-1次替換。

output：

另外， \begin{tabular}{c|c|c|c{3.5cm}}和\multirow{3}{150}{}給出錯誤，至少在這個 header 中是這樣。

Answer 2

看看新的表格陣列tabularray 。 這將為您提供更好的結果，整齊地分布行並自動處理水平線：

\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}
