Tabularray：在 longtblr 中正确行编号

Question

我正在尝试获取测试计划的编号行。预期结果是第一列中的“1”、“2”等。但是，当 tabularray 处理表格时，它会在输出任何内容之前多次增加计数器，并且在每行之间多次增加计数器，或者看起来是这样的。示例代码：

\documentclass[10pt]{article}
\usepackage{setspace}
\usepackage{geometry}
\usepackage{tabularray}
\geometry{hmargin={1.5in, 1.5in}}
\setstretch{1.2}

\usepackage[sc]{mathpazo}
\linespread{1.05}
\usepackage[T1]{fontenc}

\begin{document}

\section{Test}%
{\small
\newcounter{teststep}\setcounter{teststep}{0}
\begin{longtblr}{
    hlines, vlines,
    colspec={cXcccX},
    column{2}={halign=l, valign=m, co=5},
    column{6}={halign=l, co=2},
    row{1}={halign=c, font=\bfseries},
    rowhead=1
}
Step    & Description       & Min   & Max   & Unit  & Measured  \\
    \refstepcounter{teststep}\arabic{teststep}
        & Do a step.
            & 1 & 100   & V & ~ \\
    \refstepcounter{teststep}\arabic{teststep}\label{repstep}
        & Do another step.
            & 1 & 100   & A & ~ \\
    \SetCell[c=6]{halign=j, valign=m, wd={\linewidth-18pt}} This line explains some things.  It's a lot of text and wraps to multiple lines, and isn't numbered, and can't interrupt the numbering of steps around it.  \\
    \refstepcounter{teststep}\arabic{teststep}
        & And like in Step~\ref{repstep}, another.
            & 1 & 100   & W & ~ \\
\end{longtblr}
}

\end{document}

（我当然可以把\refstepcounter东西放进它自己的里面\newcommand{}，只是在这里写出来而已。）

结果：

如何防止数字增加？

Answer 1

tabularray多次运行表的内容，因此，如果您需要更改tabularray表内的计数器，则需要counter库来恢复它们，可以使用来启用\UseTblrLibrary{counter}。

\documentclass[10pt]{article}
\usepackage{setspace}
\usepackage{geometry}
\usepackage{tabularray}
\UseTblrLibrary{counter}
\geometry{hmargin={1.5in, 1.5in}}
\setstretch{1.2}

\usepackage[sc]{mathpazo}
\linespread{1.05}
\usepackage[T1]{fontenc}

\begin{document}

\section{Test}%
{\small
\newcounter{teststep}\setcounter{teststep}{0}
\begin{longtblr}{
    hlines, vlines,
    colspec={cXcccX},
    column{2}={halign=l, valign=m, co=5},
    column{6}={halign=l, co=2},
    row{1}={halign=c, font=\bfseries},
    rowhead=1
}
Step    & Description       & Min   & Max   & Unit  & Measured  \\
    \refstepcounter{teststep}\arabic{teststep}
        & Do a step.
            & 1 & 100   & V & ~ \\
    \refstepcounter{teststep}\arabic{teststep}\label{repstep}
        & Do another step.
            & 1 & 100   & A & ~ \\
    \SetCell[c=6]{halign=j, valign=m, wd={\linewidth-18pt}} This line explains some things.  It's a lot of text and wraps to multiple lines, and isn't numbered, and can't interrupt the numbering of steps around it.  \\
    \refstepcounter{teststep}\arabic{teststep}
        & And like in Step~\ref{repstep}, another.
            & 1 & 100   & W & ~ \\
\end{longtblr}
}
