我已经利用picture环境来对角线绘制一条规则。

调整命令中的值\put以完美对齐规则。

使用，您只需在命令（也由 提供）中{NiceTabular}使用nicematrix命令\diagbox（由 提供）。nicematrix\Blocknicematrix

\documentclass{article}
\usepackage{nicematrix}
\usepackage{booktabs}

\begin{document}

\begin{NiceTabular}{@{}lcccccc@{}}
\toprule
Link $j$ & $\theta _{j,i}$ (rad)& $d_{j,i}$ (mm)& 
     $a_{j,i}$ (mm)& $\varphi_{j,i}$ (rad) & $d_{\text{e}}$ (rad) & $\theta_{\text{e}}$ (rad) \\
\midrule
1 & 0 & 0 & 0 & $\pi/2$ &  \Block{3-2}{\diagbox{}{}}\\
2 & $\xi _{1,i}+\pi/2$ & 0 & 0 & $\pi/2$ &  \\
3 & $\xi _{2,i}+\pi/2$ & 0 & 0 & $\pi/2$ &  \\
4 & 0 & $\xi _{3,i}$ & 0 & 0 & 0 & $\pi/2$ \\
