當我將 \cmidrule 添加到表中然後嘗試在 XeLatex 中重新編譯時，它會崩潰。
它停在 \begin{document} 處：
File ended while scanning definition of \LT@xxxix. \begin{document}
Illegal parameter number in definition of \LT@xxxix. \begin{document}
Illegal parameter number in definition of \LT@xxxix. \begin{document}
File ended while scanning definition of \LT@xxxix.
我透過刪除 .aux 檔案來修復它，只要我不添加 \cmidrule，它就會再次工作。
我是 LaTeX 的菜鳥，所以感謝您的幫助。
這是它停止的地方：
...

這是我的序言：
\documentclass{book}
\usepackage[letterpaper,inner=0.75in,outer=1in]{geometry}
\usepackage{color}
\usepackage[english]{babel}
\usepackage[T1]{fontenc}
\usepackage{longtable,booktabs}
\usepackage{multirow}
\usepackage{parskip} %removes firstline indent
\usepackage{makeidx}
\usepackage{titling}
\usepackage{fontspec}
\setmainfont{Linux Libertine O}
表格範例：
\begin{longtable}[]{@{}llll@{}}

\endhead

答案1
您的表格有四列，但您要求\cmidrule跨越第 3 列到第 8 列。我不確切知道您希望它跨越哪些列，但\cmidrule(r){3-4}例如可以工作。
你可能想要\midrule：
\documentclass{book}
\usepackage[letterpaper,inner=0.75in,outer=1in]{geometry}
\usepackage{longtable,booktabs}
\begin{document}
\begin{longtable}[]{@{}llll@{}}
\toprule
centeral & personal & &\tabularnewline
\midrule
\endhead
& reflexive & &\tabularnewline
& possessive & &\tabularnewline
reciprocal & each other, one another & &\tabularnewline
relative & & &\tabularnewline
interrogative & & &\tabularnewline
demonstrative & this, that, these, those & &\tabularnewline
Indefinite & positive & universal & All, both\tabularnewline
& & & Each, every\tabularnewline
& & assertive & some\tabularnewline
& & & Multal, paucal\tabularnewline
& & & One\tabularnewline
& & & Half, several, enough\tabularnewline
& & & Other, another\tabularnewline
& & nonassertive & Any, either\tabularnewline
& negative & & No, neither\tabularnewline
\bottomrule
\end{longtable}
\end{document}
