表格中漂亮的垂直线条

请问如何在表格中创建更美观的垂直线？它们应该从第二行延伸到底线，且不重叠和留空。

\documentclass[12pt,a4paper,twoside,openright]{report}
\usepackage{multirow}

\begin{document}
\begin{table}[h!]
\centering
\small
\begin{center}
\begin{tabular}{c|cc|cc|cc}
\hline\hline
A                   &\multicolumn{2}{c}{B}     &\multicolumn{2}{c}{C}  &\multicolumn{2}{c}{D}    \\
                                   
\hline
\multirow{2}{*}{A} &\multirow{2}{*}{B} &\multirow{2}{*} {C} &\multirow{2}{*}{D} &\multirow{2}{*}{E} &\multirow{2}{*}{F} &\multirow{2}{*}{G} \\
&&&&&&\\[-5pt]

\hline
\end{tabular}
\end{center}
\end{table}

（对我来说）不清楚你喜欢在哪里画垂直线。对于水平线，有很多选择：

使用这个tabularray包，所有显示的表格都很容易编写。但是，除了显示示例外，进行其他组合也很简单...

\documentclass[12pt,a4paper,twoside,openright]{report}
\usepackage{tabularray}

\begin{document}
    \begin{table}[ht!]
    \centering
\begin{tblr}{hlines,
             colspec={c|cc|cc|cc},
             }
    \hline
A   & \SetCell[c=2]{c}  B 
        &   &  \SetCell[c=2]{c} C 
                &   &  \SetCell[c=2]{c} D 
                        &       \\
A   & B & C & D & E & F & G     \\
A   & B & C & D & E & F & G     \\
\end{tblr}
    \end{table}
    
or
    \begin{table}[ht!]
    \centering
\begin{tblr}{hline{1,Z} = 1pt, hline{2-Y}=0.2pt,
             colspec={c|cc|cc|cc},

A   & \SetCell[c=2]{c}  B
        &   &  \SetCell[c=2]{c} C
                &   &  \SetCell[c=2]{c} D

A   & B & C & D & E & F & G     \\
\end{tblr}
    \end{table}

    \centering
\begin{tblr}{hline{1,Z} = 1pt, hline{2}=0.6pt, hline{3-Y}=0.2pt,

\begin{tblr}{hline{1,Z} = 1pt, hline{2}=0.6pt, hline{3-Y}=0.2pt,
             vlines,

请尝试戒掉表格中的垂直线。相信我，垂直线是不必要的，而且大多数表格实际上没有垂直线看起来会好得多。并且，一定要使用书签软件包 -- 例如\toprule、\midrule、\cmidrule和\bottomrule-- 代替\hline和 编程补丁，例如\noalign{\smallskip}。

\documentclass[12pt,a4paper,twoside,openright]{report}
\usepackage{multirow}
\usepackage{booktabs} % <-- new
\begin{document}

\begin{table}[h!]
\centering

\begin{tabular}{c|cc|cc|cc}
\multicolumn{7}{c}{with vertical lines}\\
\hline\hline
A &\multicolumn{2}{c}{B} &\multicolumn{2}{c}{C} &\multicolumn{2}{c}{D} \\                           
\hline
\multirow{2}{*}{A} &\multirow{2}{*}{B} &\multirow{2}{*} {C} &\multirow{2}{*}{D} &\multirow{2}{*}{E} &\multirow{2}{*}{F} &\multirow{2}{*}{G} \\
&&&&&&\\[-5pt]
\hline
\end{tabular}

\begin{tabular}{@{} l *{6}{c} @{}}
\multicolumn{7}{c}{without vertical lines}\\
\toprule
