本小节所有符号依赖 amssymb 宏包。

经测试,\lvert\rvert 不需要 amssymb 宏包,只需要 amsmath 宏包,MWE:

\documentclass{article}
\usepackage{amsmath}
\begin{document}
$\lvert\rvert$
\end{document}

对应源码

\AMSSYM{\lvert} &\AMSSYM{\rvert} &\AMSSYM{\lVert} &\AMSSYM{\rVert}\\

应放到
\begin{table}[htp]
\centering
\caption{定界符。}\label{tbl:math-delims}
\begin{symbols}{*3{cl}}
\hline
\SYM{(} & \SYM{)} & \SYM{\uparrow} \\
\SYM{[} or \cmd{lbrack} & \SYM{]} or \cmd{rbrack} & \SYM{\downarrow} \\
\SYM{\{} or \cmd{lbrace} & \SYM{\}} or \cmd{rbrace} & \SYM{\updownarrow} \\
\SYM{\langle} & \SYM{\rangle} & \SYM{\Uparrow} \\
\SYM{|} or \cmd{vert} & \SYM{\|} or \cmd{Vert} & \SYM{\Downarrow} \\
\SYM{/} & \SYM{\backslash} & \SYM{\Updownarrow} \\
\SYM{\lfloor} & \SYM{\rfloor} & \\
\SYM{\rceil} & \SYM{\lceil} & & \\
\hline
\end{symbols}
\end{table}
