目录中的水平盒子过满

Question

编译代码时：

\documentclass[draft]{book}
% ---------------------------------------------
\usepackage{titletoc}
\contentsmargin{0pt}
\titlecontents{chapter}[0pc]%
{\addvspace{2.7ex}\fontsize{14}{14}\selectfont}%
{\contentslabel[\thecontentslabel]{0pc}\hspace{1pc}}%
{}%
{\nolinebreak\hfill\thecontentspage}
% ---------------------------------------------
\begin{document}
\tableofcontents
\chapter{A chapter}
\end{document}

我收到警告：

Overfull \hbox (7.04991pt too wide) detected at line 1

我应该做哪些改变才能消除警告？

Answer 1

没有0pc足够的空间容纳章节号。对于 MWE 来说，7.1pt似乎足以容纳1，但在您的实际文档中，所需的空间可能会更大。

\documentclass[draft]{book}
% ---------------------------------------------
\usepackage{titletoc}
\contentsmargin{0pt}
\titlecontents{chapter}[7.1pt]% <------------------------- change here
{\addvspace{2.7ex}\fontsize{14}{14}\selectfont}%
{\contentslabel[\thecontentslabel]{7.1pt}\hspace{1pc}}% <- and here
{}%
{\nolinebreak\hfill\thecontentspage}
% ---------------------------------------------
\begin{document}
\tableofcontents
\chapter{A chapter}
\end{document}

Answer 2

您可以使用以下方法解决 \contentspush：

\documentclass[draft]{book}
% ---------------------------------------------
\usepackage[showframe]{geometry}
\usepackage{titletoc}
\usepackage{calc}
\contentsmargin{0pt}
\titlecontents{chapter}[0pt]%
{\addvspace{2.7ex}\fontsize{14}{14}\selectfont
}%
{\contentspush{\phantom{11}}\contentslabel[\hfill\thecontentslabel]{2em}\hspace{1pc}}%
{}%
{\nolinebreak\hfill\thecontentspage}
% ---------------------------------------------
\begin{document}

\tableofcontents
\chapter{A First Chapter}
\setcounter{chapter}9
\chapter{Another Chapter}

\end{document}
