LaTeX \rule 填充该行

发布于 2024-08-27 23:35:28 字数 419 浏览 4 评论 0原文

为什么以下命令不会生成填充行尾之前的空间的水平线?

Hello \rule[0.5em]{\fill}{1pt}

据我了解,这应该打印文本“Hello”,后跟一条延伸到行尾的水平线,类似于宏 \hfill ,它实际上是相当于\hspace\fill。 – 但实际上,这个命令只是产生文本“Hello”,没有规则。

我知道效果可以由 \hrulefill 产生,但不能在这里使用,因为我想要一个 raised 规则和 \hrulefill不能与 \raisebox 一起使用,并且我希望我的规则悬挂在基线之上(最好位于该行的中间)。

Why does the following command not produce a horizontal rule filling the space until the end of the line?

Hello \rule[0.5em]{\fill}{1pt}

It is my understanding that this should print the text “Hello” followed by a horizontal rule that extends until the end of the line, analogously to the macro \hfill which is effectively equivalent to \hspace\fill. – But in effect, this command just produces the text “Hello”, no rule.

I am aware that the effect can be produced by \hrulefill but it can’t be used here because I want a raised rule and \hrulefill doesn’t work together with \raisebox and I want my rule to hang above the baseline (at best in the middle of the line).

对于为什么您提供的命令不起作用,我没有令人满意的答案,但我可以提供有效的解决方法。将其放入

% Raised Rule Command:
%  Arg 1 (Optional) - How high to raise the rule
%  Arg 2            - Thickness of the rule
\newcommand{\raisedrule}[2][0em]{\leaders\hbox{\rule[#1]{1pt}{#2}}\hfill}

文档的前言中,然后您就可以完成您希望的事情:

Hello \raisedrule[0.5em]{1pt}

I don't have a satisfying answer as to why the command you presented doesn't work, but I can offer an effective workaround. Put

% Raised Rule Command:
%  Arg 1 (Optional) - How high to raise the rule
%  Arg 2            - Thickness of the rule
\newcommand{\raisedrule}[2][0em]{\leaders\hbox{\rule[#1]{1pt}{#2}}\hfill}

into your document's preface, and then you can accomplish what you were hoping to with:

Hello \raisedrule[0.5em]{1pt}
街角迷惘 2024-09-03 23:35:28

水平尺高度为 1pt,并升高 1.5pt。

Hello \leaders\vrule height 2.5pt depth -1.5pt \hfill \null

The horizontal rule of 1pt height and raised by 1.5pt.

Hello \leaders\vrule height 2.5pt depth -1.5pt \hfill \null

有一个名为 ulem 的包,它

% !TEX encoding = UTF-8 Unicode
% !TEX TS-program = xelatex
\documentclass{article}
\usepackage[normalem]{ulem}

\begin{document}
normal text \uline{\textit{underline text}\hfill}
\end{document}

会生成

underline

为了满足您的好奇心, ulem 包的选项 normalem 可以防止 ulem 使用 \em\emph 生成额外的下划线。

There is a package called ulem which does this

% !TEX encoding = UTF-8 Unicode
% !TEX TS-program = xelatex
\documentclass{article}
\usepackage[normalem]{ulem}

\begin{document}
normal text \uline{\textit{underline text}\hfill}
\end{document}

which will produce

underline

For your curiosity, the option normalem for package ulem prevents ulem to produce extra underline with \em or \emph.

您可以使用命令 \hrulefill 来完成此操作
请参阅http://en.wikibooks.org/wiki/LaTeX/Lengths#Fill_the_rest_of_the_line

You can do this with the command \hrulefill
