对齐 tabularx 环境的左右两侧（对齐）

我正在使用tabularx包和环境来列出文本中的内容。

代码如下。

\documentclass[10pt]{book}
\usepackage{newpxtext,newpxmath}
\linespread{1.05}
\usepackage{tabularx}
\setlength{\parindent}{0pt}

\begin{document}
\par a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a
\vspace{10pt} \par
\begin{tabularx}{\textwidth}{@{}lX}
    \vspace{10pt} No. 1. & a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a  \\
    \vspace{10pt} No. 2. & a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a  \\
    \vspace{10pt} No. 3. & a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a  \\
\end{tabularx}
\par a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a
\end{document}

输出如下。

可以看出，列出的上下文只与正常文本左对齐，而没有与正常文本右对齐。

有人知道如何解决这个问题，或者是否有其他更好的包或环境来实现这种性能？

你可能会使用

\begin{tabularx}{\textwidth}{@{}lX@{}}

但我相信你可以做得更好enumitem。

\documentclass[10pt]{book}
\usepackage{newpxtext,newpxmath}
\usepackage{enumitem}

\linespread{1.05}

\begin{document}

a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a

注意No.\ \arabic*.使用反斜杠空格，因此句号不会被解释为句子结束。
