MWE:
\documentclass[10pt]{article}
\usepackage{amsmath}
\begin{document}
\usepackage{tabularx}
\begin{center}
\begin{tabular}{|l|l|l|l|l|}
\hline monomial($Y_i$) & i & $SU(n)$ & ~ & ~ \\ \hline
$ i\langle V^{\mu\nu}\{u^\mu u^\nu,u^\alpha u^\alpha\} \rangle$ & 1 & 4 & $i V^{\alpha} \left(-\nabla^{\mu}{u^{\mu}} u^{\alpha} u^{\nu} u^{\nu}-u^{\mu} \nabla^{\mu}{u^{\alpha}} u^{\nu} u^{\nu}-u^{\alpha} u^{\mu} \nabla^{\nu}{u^{\nu}} u^{\mu}-u^{\mu} u^{\mu} u^{\nu} \nabla^{\nu}{u^{\alpha}}+\nabla^{\mu}{u^{\alpha}} u^{\mu} u^{\nu} u^{\nu}+u^{\alpha} \nabla^{\mu}{u^{\mu}} u^{\nu} u^{\nu}+u^{\mu} u^{\mu} \nabla^{\nu}{u^{\alpha}} u^{\nu}+u^{\alpha} u^{\mu} u^{\mu} \nabla^{\nu}{u^{\nu}}\right)$ & ~ \\ \hline

我想让这段公式自动换行(不在乎是否对齐,只要达到一定的长度能自动换行即可)
