问题
我如何计算标题后的距离，以便我可以将节点放置在标题规则所在的位置？
例子
我希望有一个栏从页面的右上角向下移动到标题规则（无论我对定义做了什么更改，它都应该完全对齐titlesec）。如果有人能帮助我将章节编号与章节标题对齐，我将不胜感激。
示例代码
\documentclass[10pt]{article}
\usepackage{fontspec}
% Title Styles
\usepackage[compact,explicit,noindentafter]{titlesec}
\usepackage{tocloft}
\usepackage{needspace}
\usepackage{tikz} % Absolute positioning, advanced vector graphics
\usepackage{tikzpagenodes} % Adds nodes around page boxes (e.g. body)
\usetikzlibrary{calc,positioning,decorations} % Extensions for tikz (increase compilation time)
\usepackage{anyfontsize}
\newcommand{\tikztitlenumber}[1]{%
\begin{tikzpicture}[remember picture, overlay,baseline]
\node [inner sep=0pt, outer sep=0pt,anchor=base] (titlenumber) at (current page text area.north east) {#1};
\path [fill=blue] (current page.north east) rectangle ($ (titlenumber.south east -| current page.east) + (-3mm,-\baselineskip) $);
\end{tikzpicture}}
% SECTION
\titleformat{\section}[hang]{\needspace{6cm}\color{blue}\Huge\bfseries}{\tikztitlenumber{\thesection}}{0pt}{#1}[\vspace{0mm}\titlerule]
\begin{document}
\section{Hello}
\end{document}

由于没有tikz专家给出解决方案，因此这里是非专家的尝试......
\documentclass[10pt]{article}
\usepackage{fontspec}
% Title Styles
\usepackage[compact,explicit,noindentafter]{titlesec}
\usepackage{tocloft}
\usepackage{needspace}
\usepackage{tikz} % Absolute positioning, advanced vector graphics
\usepackage{tikzpagenodes} % Adds nodes around page boxes (e.g. body)
\usetikzlibrary{calc,positioning,decorations} % Extensions for tikz (increase compilation time)
\usepackage{anyfontsize}
\usepackage{lipsum}
\newcommand{\tikztitlebar}{%
\begin{tikzpicture}[remember picture, overlay,baseline]
\node (titlenumber) {};
\path [fill=blue] (current page.north east) rectangle ($ (titlenumber.south east -| current page.east) + (-3mm,-0.4pt) $);
\end{tikzpicture}}
% SECTION
\titleformat{\section}[hang]
{\needspace{6cm}\color{blue}\Huge\bfseries}
{}
{0pt}
{#1\hfill\thesection\tikztitlebar}
[\vspace{0mm}\titlerule]
\begin{document}
\lipsum[1]
\section{Hello}
\end{document}
