tabularx 周围不需要不同的 parskip 长度

Question

我尝试使用 tabularx 环境将我的长论文标题对齐到冒号处，如下图所示。我希望每个条目之间的垂直间距为一个 parskip，就像在普通文本中使用的一样（例如：大学和部门之间的间距）。不知何故，如果仔细观察，间距看起来通常非常不一致。我知道 parskip 是可拉伸的长度，但我如何才能实现均匀的垂直间距，尤其是在 tabluarx 环境中。谢谢！

注意：文本将被放入框架环境中，但我不认为这是这里的问题。

MWE（带有编译的xelatex的scrbook类）：

\documentclass[
    a4paper,
    10pt,
    parskip=half,
]{scrbook}

\usepackage[showframe]{geometry}
\usepackage{setspace}
\usepackage{tabularx}

\onehalfspacing

\newlength{\defaulttabcolsep}
\setlength{\defaulttabcolsep}{\tabcolsep}

\begin{document}
Author:~Author \hfill Type of the work: Thesis\\[\parskip]
\setlength\tabcolsep{0pt}
\begin{tabularx}{\linewidth}{l X}
    Title:~ & Tabularx environment is used to align long titles at the colon Tabularx environment is used to align long titles at the colon\\[\parskip]
    Test & Test\\[\parskip]
\end{tabularx}
\setlength\tabcolsep{\defaulttabcolsep}
Date:~\today\\[\parskip]

Department:~Department
\end{document}

编辑：

我现在将linegoal代码放入环境中framed。不幸的是，有时它需要在我的主文档中进行 6 次或更多次迭代才能终止编译，并且parbox不再完全对齐，这可能表明剩余线宽计算不正确。

有人有什么想法吗，是否采用表格方法或其他方法？

Answer 1

哦，天哪！ 的常见问题是parskip=half，将\parfillskip设置为非零自然宽度以试图隐藏问题parskip造成的问题。

嗯，我认为没有必要\linegoal使用 ，因为\linewidth在另一种情况下，您可以简单地使用 。由于\parfillskip，您会得到一个 10pt 的溢出框，但是没有 也很容易处理tabularx。

\documentclass[
    a4paper,
    10pt,
    parskip=half,
]{scrbook}

\usepackage{setspace}
\usepackage{tabularx}
\usepackage{framed}

\newcommand{\longhang}[2]{%
  \par
  \settowidth{\dimen0}{#1: }%
  \hangindent=\dimen0 \hangafter=1
  \mbox{#1: }\ignorespaces #2\par
}


\onehalfspacing

\begin{document}

Author:~Author \hfill Type of the work: Thesis{\parfillskip=0pt\par}

\longhang{Title}{
  Tabularx environment is not used to align long titles at the colon
  Tabularx environment is not used to align long titles at the colon
}

Date:~\today

\begin{oframed}
  Author:~Author \hfill Type of the work: Thesis{\parfillskip=0pt\par}

\longhang{Title}{
  Tabularx environment is not used to align long titles at the colon
  Tabularx environment is not used to align long titles at the colon
}

Answer 2

以下是另一个建议\@hangfrom：

\documentclass[
  %a4paper,% default
  10pt,
  parskip=half,
]{scrbook}

\usepackage[showframe]{geometry}
\usepackage{setspace}
\usepackage{framed}

\onehalfspacing

\begin{document}
\begin{oframed}
  \setlength{\parfillskip}{0pt plus 1fil}
  Author:~Author \hfill Type of the work: Thesis

  \makeatletter
  \@hangfrom{Title:~}{Tabularx environment is used to align long titles at the colon Tabularx environment is used to align long titles at the colon}
  \makeatother

  Date:~\today

  University:~University

  Department:~Department
\end{oframed}
\end{document}

补充说明：选项parskip=half设置\parfillskip为1em plus 1fil。如果段落的最后一行应该跨越整个宽度，但使用当前的缩进和段落间距离设置，则必须在本地更改\parfillskip为0pt plus 1fil。或者您可能想使用选项parskip=half-。

Answer 3

由于我最近的评论，我不完全确定这是否能满足您的需求，但我的建议是使用包装\parbox的宽度。\linegoallinegoal

\documentclass[
    a4paper,
    10pt,
    parskip=half,
]{scrbook}

\usepackage[showframe]{geometry}
\usepackage{setspace}
\usepackage{linegoal}

\onehalfspacing

\begin{document}
Author: Author \hfill Type of the work: Thesis\\[\parskip]
Title: \parbox[t][2\baselineskip]{\linegoal}{This is a parbox used with the width \texttt{\textbackslash linegoal} which I am making extra long so you can see how it breaks}\\[\parskip]
Date: \today\\[\parskip]
University: University of \LaTeX\\[\parskip]
Department: Department of Typesetting\\[\parskip]

\end{document}

然后您可以\\[\parskip]在任何地方使用（或者只是在除第一行之外的所有地方使用段落分隔符，因为出于\hfill我无法弄清楚的原因，它会出现错误）。

您需要至少编译两次才能\linegoal正常工作。
