为什么表格在描述环境中没有与文本对齐？我希望它具有与文本相同的左缩进和宽度。这可能吗？
\documentclass[a4paper,oneside]{book}
\usepackage[paper=a4paper, left=1.5cm, right=1cm, top=1.7cm, bottom=2.5cm]{geometry}
\usepackage{ltablex}
\usepackage[utf8]{inputenc}
\parindent=0pt
\begin{document}
\textbf{Just an example}
\begin{description}
\item[\textit{Lorem Ipsum is}] \hfill \linebreak
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard.

答案1
该ltablex包将 tabularx “转换”为 longtable。默认情况下，longtable 位于文本正文的中心。如果您希望它沿着描述的左边距对齐，请设置\LTleft：
\documentclass[a4paper,oneside]{book}
\usepackage{ltablex}
\begin{document}
\begin{description}
\item[\textit{Lorem Ipsum is}] \hfill \linebreak
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard.
\begin{tabularx}{\linewidth}{|X|} \hline
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard.
\end{tabularx}%
\LTleft=\leftmargin
\begin{tabularx}{\linewidth}{|X|} \hline
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard.
\end{tabularx}%
\end{description}
\end{document}
答案2
由于您希望您的tabularx环境忽略的description缩进，请将其替换\linewidth为\textwidth。
