我的表格中的箭头不直。如何才能使它们变直？

\documentclass{ieeeaccess}
\usepackage{tikz}
\usetikzlibrary{tikzmark}
\begin{document}
    \begin{table*}[htb]
    \setlength\extrarowheight{2pt}
    \centering
    \begin{tabular}{|ll|c:c|c|}\cline{1-5}
    \multicolumn{2}{|c|}{\multirow{2}{*}{… }} &
    \multicolumn{3}{c|}{ …}\\\cline{3-5} 
    
                    &  & \multicolumn{1}{c}{\textsc{..}}  &  & {\textsc{..}}    \\ \cline{1-5} 
                    &   &   ……   &     \\ 
    
    \leftpointright &  … &  \tikzmark{aa}  $ 1,2 $ \tikzmark{a}   & $ 3,4 $ \tikzmark{b}  & \tikzmark{cc} $ 5,6 $ \tikzmark{c}      \\  &     &     &    &       \\\cline{1-5}
