Answer 1

如果我理解正确的话，那么您在专栏听众中寻找\rowcolor。使用``thead{...} this doesnt wotk well, so i sugest replace it withmulticolumn` 环境：

\newcommand\mcx[2]{\multicolumn{1}{#1}{\textbf{#2}}}

完整的 mwe 是：

\documentclass{article}
\usepackage{ltablex}
\newcommand\mcx[2]{\multicolumn{1}{#1}{\textbf{#2}}}
\usepackage[table]{xcolor}
\usepackage{pdflscape}
