在一个大型项目中工作，其中定义了一些用于表格的命令。我将它们列在下面。使用它们，我尝试创建一个包含多行且仍能正确对齐其他单元格的表格：
可以看出，我设法获得了多行，但没有获得正确的单元格行和/或 X 的居中。我做错了什么？
非常感谢！
以下是 MWE：
\documentclass{report}
\usepackage[utf8]{inputenc}
\usepackage{diagbox}
\usepackage{multirow}
% for loop - table 1
\usepackage{forloop}
\newcounter{loopcntr}
\newcommand{\rpt}[2][1]{%
\forloop{loopcntr}{0}{\value{loopcntr}<#1}{#2}%
}
\newcommand{\on}[1][1]{
\forloop{loopcntr}{0}{\value{loopcntr}<#1}{&\scriptsize X}
}
\newcommand{\off}[1][1]{
\forloop{loopcntr}{0}{\value{loopcntr}<#1}{&}
}
% extra table 1

通过使用tabularray包并x在需要的地方插入，表的代码可以大大简化：
\documentclass{report}%
%---------------- show page layout. don't use in a real document!
\usepackage{showframe}
\renewcommand\ShowFrameLinethickness{0.15pt}
\renewcommand*\ShowFrameColor{\color{red}}
%---------------------------------------------------------------%
