删除表格行并分别给两个表格添加标题

Question 1

（1）第一个问题。要使两个subtables(a) 和 (b) 共享一个标题，可以将以下结构与包一起使用subcaption：

\begin{table}[ht!]
    \centering  
    \begin{subtable}{\linewidth}    
        \footnotesize \centering
        \begin{tabular}{|c| c c c c c c c|}     
        ...
        \end{tabular}
        \subcaption{Subtable I}\label{subtab:a}
    \end{subtable}% 
    \bigskip
    
    \begin{subtable}{\linewidth}    
        \footnotesize \centering
        \begin{tabular}{|c| c c c c c c c|}     
        ...
        \end{tabular}
        \subcaption{Subtable II}\label{subtab:b}
    \end{subtable}%
        \caption{Table in which the \emph{Weight Factors} are depicted  ...}
        \label{tab:WF_tab}
\end{table}

（2）要使表格适合页面且字体易读，需要进行更多更改，主要是使用三行作为标题（包makecell）并简化列定义（包array）。还添加了包siunitx以包含适当的 SI 单位。

（3）第二个问题。删除整行的解决方案来自删除整行

用标记红线的起点\StrikeStarts{<cell contents>}，用标记红线的终点\StrikeEnds{<cell contents>}

（半）最终结果

这是所使用的代码。

（仍然需要使表格自动适应文本的宽度，对齐小数点，改进“线条”，但这些超出了问题的范围）
