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}
