精美的标题对齐

Question

这是我的双面文档的页眉。 如您所见，当数字增加时，将页码与章节名称分开的垂直线会向内移动一点。我希望将此线的位置固定并与页面的文本框对齐。这是我的代码：

\documentclass [11pt, a4paper, twoside, openright]{book}

\usepackage[english]{babel}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{geometry}
\usepackage{xcolor}

\geometry{
inner=2.4cm, % Inner margin
outer=4cm, % Outer margin
top=3.5cm, % Top margin
bottom=3cm, % Bottom margin
heightrounded,
bindingoffset=4mm,
showframe,
}

\usepackage{fancyhdr}
\pagestyle{fancy}
\renewcommand{\chaptermark}[1]{\markboth{#1}{}}
\renewcommand{\sectionmark}[1]{\markright{\thesection\ #1}}
\fancyhf{}
\fancyhead[LE]{\thepage\hspace{7pt}\textcolor{gray}{|}\hspace{5pt}\nouppercase{\textcolor{gray}{\leftmark}}}
\fancyhead[RO]{\nouppercase{\textcolor{gray}{\rightmark}}\hspace{5pt}\textcolor{gray}{|}\hspace{7pt}\thepage} 

Answer 1

如果要在页边距中偏移页码，则需要使用\fancyhfoffset。将页码括在与偏移量一样宽的框中（并且足够大以容纳最宽的罗马页码）。

\documentclass [11pt, a4paper, twoside, openright]{book}

\usepackage[english]{babel}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{geometry}
\usepackage{xcolor}
\usepackage{fancyhdr}

\usepackage{kantlipsum}

\geometry{
  inner=2.4cm, % Inner margin
  outer=4cm, % Outer margin
  top=3.5cm, % Top margin
  bottom=3cm, % Bottom margin
  headheight=13.6pt,
  heightrounded,
  bindingoffset=4mm,
  showframe,
}

\pagestyle{fancy}
\renewcommand{\chaptermark}[1]{\markboth{#1}{}}
\renewcommand{\sectionmark}[1]{\markright{\thesection\ #1}}
\fancyhf{}
\fancyhfoffset[LE]{20pt}
\fancyhfoffset[RO]{20pt}
\fancyhead[LE]{%
  \makebox[20pt][l]{\thepage}%
  {\color{gray}\makebox[0pt]{\textbar}\hspace{5pt}\nouppercase{\leftmark}}%
}
\fancyhead[RO]{%
  {\color{gray}\nouppercase{\rightmark}\hspace{5pt}\makebox[0pt]{\textbar}}%
  \makebox[20pt][r]{\thepage}%
}

\begin{document}

\frontmatter

\chapter{Introduction}
\section{Abstract}

\kant[1-40]

\end{document}

我还将栏设置在零宽度框中。
