是否可以将两端对齐的文本块最后一行的文本右对齐？

有没有办法让文本右对齐，同时又能保证两端对齐？这特别适用于段落的最后一行，该行通常是左对齐的，或者例如非常短的一行段落，虽然是两端对齐的，但也会出现左对齐的情况。

谢谢您的帮助！ ：）

答案1

TeX\leftskip基元寄存器保存段落行左侧使用的跳过。跳过可以是可拉伸的，例如 0pt plus1fil。TeX 基元寄存器\rightskip保存段落行右侧使用的跳过。它可以是“负可拉伸的”。这并不意味着可收缩，但它会从中消除正可拉伸量\leftskip。TeX\parfillskip基元寄存器默认设置为（例如，通过纯 TeX）0pt plus1fil。它被添加到段落最后一行的末尾。如果我们设置：

\leftskip=0pt plus1fil
\rightskip=0pt plus-1fil

test text ...
\bye

然后段落的所有行（除了最后一行）都只有\leftskip左侧和\rightskip右侧。它们的和为零，因此只有单词之间的 glu 用于对齐。最后一行有 -1fil 形式和右侧的\rightskip1fil 。它们的和为零。但是还有另一个 1fil 。这个跳过被拉伸，结果就像这里的另一个答案中所示的那样。这个另一个答案使用 LaTeX 特定的语法来设置 TeX 原始寄存器。\parfillskip\leftskip

答案2

你只需要平衡跳跃，

在此处输入图片描述

\documentclass{article}

\begin{document}

\setlength\leftskip    {\stretch{1}}
\setlength\parfillskip {\stretch{1}}
\setlength\rightskip   {\stretch{-1}}

wipet 的答案起了作用。我只是想发布一个带有工作环境定义的小示例。

\documentclass{book}
\usepackage{lipsum}
\usepackage{ragged2e}

\newenvironment{justifyright}%
               {\justifying
                \leftskip=0pt plus1fil
                \rightskip=0pt plus-1fil}%
               {\par}

\begin{document}

\mainmatter
\begin{justifyright}
    \lipsum[1]
    \lipsum[2]
    \lipsum[3]
\end{justifyright}

\lipsum[1]
\lipsum[2]
\lipsum[3]


\end{document}
