表格中的多个箭头

表格中的多个箭头

我目前有下表:在此处输入图片描述

对应下面的代码:

\begin{table}[h] 
\scriptsize
 % \centering
  \caption{Permutation Importance}
\resizebox{\textwidth}{!}{\begin{tabular}{lcccccccc} \toprule
 &  \ldots   & $\text{M2}^{(\text{SMB})}$ & $\text{M2}^{(\text{HML})}$ & $\text{DJI}^{(\text{MOM})}$ & $\text{DJI}^{(\text{SMB})}$ & $\text{DJI}^{(\text{HML})}$ & $\text{CAPE}^{(\text{MOM})}$ & \ldots  \\ \midrule
1 & \ldots   & 0.20 & 1.93 & 0.10 & 0.32 & 1.39 & -2.50 & \ldots \\

$N_{t} - 1$  & \ldots   & 0.24 & 1.64 & 0.15 & -1.77 & 21.74 & -1.79  & \ldots \\ 
$N_{t}$  & \ldots   & 0.24 & 1.64 & 0.15 & -1.77 & 21.74 & -1.79  & \ldots \\ 

\bottomrule
\end{tabular}} \label{tab:fac_char}
\end{table}

现在我的目的是为 DJI^(MOM)、DJI^(SMB) 和 DJI^(HML) 画箭头,以表明它们正在同时随机重新洗牌。我在网上看到了下面的图片,它说明了我对 1 列的意思: 在此处输入图片描述

我想我必须使用 Tikz 包,但我不知道从哪里开始。

这是一个起点。
