包ltablex是包tabularx结束的组合longtable。通过它你可以获得：
\documentclass{article}
%\usepackage{tabularx} it is suficient to load it once (by ltablex)
\usepackage{amsmath}
\usepackage[table]{xcolor}
\usepackage{makecell, multirow, rotating, ltablex}
% "ltablex" merge features of `tabularx" and "longtable"
% they are not need to be separately loaded
\keepXColumns % preserve `X` column features when content is shorter
% than cell determined by "tabularx" algorithm
\usepackage{enumitem}
\begin{document}
%\begin{center} % not needed
%\settowidth\rotheadsize{List of Abbreviation/acronym} % not needed,
% you haven't rotated cells
