如何在甘特图中添加水平线？

我正在尝试使用pgfganttOverleaf 中的包制作甘特图。我有一个问题尚未解决。我想在每个组下面添加水平线。为了更好地解释自己。我得到了这个： 我得到了什么

我想要这个： 我想要的是

这是我正在使用的甘特图规格的开头：我将其添加到带有的论文文档中\documentclass{book}。我已经包含了我认为与甘特图相关的软件包，以简化项目中包含的大量软件包。

\documentclass{book}
\usepackage{pgfgantt}
\usepackage{graphicx}
\usepackage{xcolor}
\usepackage{import}

\ganttset{group/.append style={black}, milestone/.append style={red},
 progress label node anchor/.append style={text=red}}

\begin{document}

 \begin{ganttchart}[%Specs
 y unit title=0.5cm,
 y unit chart=0.7cm,
 hgrid={*1{black}, *7{dotted}, *1{black},  *6{dotted}},
 vgrid, 
 x unit=0.5cm,
 title height=1,
 title label font=\bfseries\footnotesize,
 bar/.style={fill=lightgray},
 bar height=0.4,
 group right shift=0,
 group top shift=0.7,
 group height=.3,
 group peaks width={0.2},

 bar label node/.append style={text width=15cm},
 group label node/.append style={text width=15cm},
 milestone label node/.append style={text width=15cm},
 bar label node/.append style={align=left, text width=width("longest text I have")},
 ]{1}{12}  

\ganttgroup[inline=false]{{Obj. 1: Some text in here}}{1}{3}\\
\ganttbar[inline=false]{Task 1.1: Some text in here}{1}{1}\\
\ganttbar[inline=false]{Task 1.2: Some text in here}{1}{2}\\
\ganttbar[inline=false]{Task 1.3: Some text in here}{2}{2}\\
\ganttbar[inline=false]{Task 1.4: Some text in here}{2}{3}\\
\ganttbar[inline=false]{Task 1.5: CSome text in here}{3}{4}\\
\ganttbar[inline=false]{\textit{Paper 1}}{4}{4}\\
\ganttnewline


 \end{ganttchart}
 \end{document}

\ganttnewline我想在空格后在文本中添加一条水平线。

欢迎使用 TeX.SE。可以使用 添加线条\ganttnewline，它接受可选的格式化键，例如线条粗细和颜色，如下所示： 。如果不为使用的命令\ganttnewline[very thick, blue]设置任何键，则不会绘制任何线条。请参阅手册的第 2.4 节。\draw\ganttnewlinepgfgantt

通过测量最长条形标签的长度来调整线的左起始位置，然后将其存储在\myleft像这样： \pgfmathsetmacro\myleft{width("Task 1.1: Some text in here")+10pt}。然后我们更新\ganttnewline命令以用作\myleft线的起点（MWE 中的注释指示此替换发生的位置）。

其他清理工作包括删除两个bar label node键中的一个，因为一个键有text width=15cm，另一个键正在测量宽度，如上所述。通常，您只需定义最长标签的宽度，无论是group label、bar label还是milestone label。这里，有最长的标签，因此和bar label的文本宽度设置是多余的，也可以删除。group label nodemilestone label node
