在用户定义环境中在 tabularray 中创建条目的宏

Question

我需要一个宏来在表中创建条目（行）。如提议的那样这里我成功地将这个environ包与那个包一起使用tabu。由于tabu没有维护，我决定切换到tabularray这个包。

不幸的是，tabularray使用宏并不容易。我尝试将命令传递\BODY给expand选项，但没有成功：

\documentclass[a4paper,10pt]{article}
\usepackage[utf8]{inputenc}
\usepackage{xcolor}
\usepackage{tabularray}
\usepackage{environ}

\NewEnviron{tabletest}{
  \begin{tblr}[expand=\BODY]
    {colspec = {X[6,l,m]X[1,c,m]X[0.5,c,m]X[1,r,m]},
    rowsep = {3mm},
    rowhead = 1, rowfoot = 1,
    row{odd} = {gray!20}, row{even} = {gray!5},
    row{Z} = {gray} % last line
    }
    \SetRow{12mm, c, bg=gray, font=\large\bfseries} Title & A & B & C \\
    
    \BODY

    This & is & last & row \\
  \end{tblr}
}

\newcommand{\addrow}[4]{#1 & #2 & #3 & #4 \\}

\begin{document}

\begin{tabletest}
  This & is & a & line \\
  This & is & a & line \\
%  \addrow{This}{is}{a}{test}       <-- not working !
\end{tabletest}

\end{document}

我想用\addrow宏创建所有线条。我该怎么做？谢谢您的帮助。

类似这样的事情可能会有效：

\documentclass[a4paper,10pt]{article}
\usepackage{xcolor}
\usepackage{tabularray}

\NewDocumentEnvironment{tabletest}{+b}
 {
  \begin{tblr}[expand=\addrow]
    {colspec = {X[6,l,m]X[1,c,m]X[0.5,c,m]X[1,r,m]},
    rowsep = {3mm},
    rowhead = 1, rowfoot = 1,
    row{odd} = {gray!20}, row{even} = {gray!5},
    row{Z} = {gray} % last line
    }
    \SetRow{12mm, c, bg=gray, font=\large\bfseries} Title & A & B & C \\
    
    #1

    This & is & last & row \\
  \end{tblr}
}{}

\newcommand{\addrow}[4]{#1 & #2 & #3 & #4 \\}

\begin{document}

\begin{tabletest}
  This & is & a & line \\
  This & is & a & line \\
  \addrow{This}{is}{a}{test}       
\end{tabletest}

\end{document}
