tabularray无法输出latex3变量

在tblr里面执行逻辑操作的时候遇到了问题

1. 如何显示l3变量？使用gset
2. 计数器失效？

计数器MWE：

\documentclass[zihao=-4,a4paper,punct=kaiming,oneside]{ctexart}
\usepackage{tabularray}
\UseTblrLibrary{counter}
% % 逻辑页计数器
\newcounter{lfrmc}
\setcounter{lfrmc}{0}
\NewExpandableDocumentCommand{\spl}{}
{%
    \thelfrmc%
    \addtocounter{lfrmc}{1}
}
\NewExpandableDocumentCommand{\lfrmh}{}
{%
    empty&ok&\spl\\
}

\begin{document}
\begin{longtblr}[expand=\expanded]{
    colspec={|X|X|X|}
}
\expanded{\lfrmh}
\expanded{\lfrmh}
\expanded{\lfrmh}
a&b&c\\\hline
\end{longtblr}
最右边一列希望是：0、1、2……递增
\end{document}
