我需要在一个文档中标记两种不同类型的更改，但我不能使用不同的颜色。到目前为止，我发现的唯一解决方案是更改\changebarwidth，但分别使用细的和粗的更改栏并不是满足我需求的“完美”解决方案。相反，我正在寻找一种解决方案来更改更改栏的类型，例如使用“双更改栏”（两个平行的更改栏）或虚线更改栏或类似的东西。我尝试过使用嵌套更改栏，但我无法\changebarsep仅将第二个更改栏交替。是否有可行的解决方案来获取不同的更改栏？
更新：该解决方案也适用于超过两页（或更多页）的更改。
以下是示例代码：
\documentclass{article}
\usepackage{changebar}
\setlength\changebarsep{30pt}
\begin{document}
This is some text.\\
\cbstart
Here is some text that has to be marked with the usual changebar.
\cbend
\bigskip
This is some further text.\\
\cbstart
\setlength\changebarsep{15pt} %this seems not to have any effect at all
\cbstart
Here is some text that has to be marked with a different changebar.
\cbend
\cbend
\end{document}```

tikz 解决方案：
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{calc,positioning}
\newcommand{\tikzmark}[1]{\begin{tikzpicture}[overlay,remember picture] \coordinate (#1);\end{tikzpicture}}
\makeatletter
\newcommand{\myfsize}{\f@size pt}
\makeatother
\newcommand{\cbstart}[1][1]{\xdef\myArg{#1}\tikzmark{cbstart}}
\newcommand{\cbend}{\tikzmark{cbend}\foreach \i in {1,...,\myArg}{\begin{tikzpicture}[overlay,remember picture]\draw let \p1=(cbstart),\p2=(cbend),\p3=(current page.east) in ({\x3-2cm+\i*0.1cm},{\y1+\myfsize})--({\x3-2cm+\i*0.1cm},{\y2});\end{tikzpicture}}}
\begin{document}
This is some text.\\
\cbstart
Here is some text that has to be marked with the usual changebar.
\cbend
\bigskip
This is some further text.\\
