我想将包括水平线的目录标题（使用tocloft）与简介章节标题（使用titlesec）垂直对齐。但是，我很困惑，因为这两个包似乎测量不同的空间。我可以通过反复试验来匹配它们，但有人能告诉我如何准确测量吗？或者我应该尝试不同的方法？
\documentclass[draft,a4paper,11pt,oneside]{book}
\usepackage{lipsum}
\usepackage{sectsty} % Used for sectionrule in ToC
\usepackage{titlesec}
%---Change Margins
\usepackage[DIV=9,BCOR=2mm,headinclude=true,footinclude=false]{typearea}
%---Chapter Title Format
\titleformat{\chapter}[display]{\usefont{T1}{qhv}{b}{n}\selectfont\huge}
{\chaptertitlename\ \thechapter}{22pt}{\huge}[\vspace{1.5ex}{\titlerule[1pt]}]
\titlespacing*{\chapter}{0mm}{-22pt}{40pt} % Removes gap above chapters.
%---ToC Format
\usepackage{tocloft}
\renewcommand{\cfttoctitlefont} % ToC title
%---How to match sectionrule with the 'Introduction' chapter?
{\usefont{T1}{qhv}{b}{n}\selectfont\huge\sectionrule{0ex}{0pt}{-2ex}{1pt}}
\renewcommand{\cftchapfont} % chapter titles

\renewcommand{\cftsecpagefont} % section page numbers
{\cftsecfont}
%---Removes gap above TOC. How to match 'Contents' with chapter 'Introduction'?
\setlength{\cftbeforetoctitleskip}{-22pt}

您必须tocloft使用该titles选项进行加载（参见手册中的第 2.1 节）。
\documentclass[draft,a4paper,11pt,oneside]{book}
\usepackage[DIV=9,BCOR=2mm,headinclude=true,footinclude=false]{typearea}
\usepackage{titlesec}

\usepackage{lipsum}
%---Chapter Title Format
\titleformat{\chapter}[display]
{\usefont{T1}{qhv}{b}{n}\selectfont\huge}
{\chaptertitlename\ \thechapter}
{22pt}
{\huge}
[\vspace{1.5ex}{\titlerule[1pt]}]
\titlespacing*{\chapter}{0mm}{-22pt}{40pt} % Removes gap above chapters.
\addtocontents{toc}{\protect\vspace{-10pt}} % remove gap before first chapter
