使用自定义计数器抑制表头中的计数器标签

Question

我创建了一个自定义环境，让表格的第一列成为带有标签的计数器，可以在整个文本中引用。我不知道如何隐藏标题列中的计数器标签 (1)。以下是我尝试的方法：

\documentclass{article}
\title{MWE of Issue}
\author{me}

\usepackage{tabularx}

% this is the custom counter
\newcounter{slots}
\newenvironment{planar}
{
\begin{flushleft}
\begin{tabular}{>{(\refstepcounter{slots}\theslots)}rlll}
    \setcounter{slots}{0} %resetting counter after header
 Pos.    & Type  & Elements  & Forms \\
}
{
\end{tabular}
\end{flushleft}
}


\begin{document}
\maketitle

Some text here. 

% here's a table using the custom counter
\begin{planar} 
    \label{a}     & itemA          & aboutA & moreA \\
    \label{b}     & itemB          & aboutB & moreB \\
    \label{c}     & itemC          & aboutC & moreC \\
    \label{d}     & itemD          & aboutD & moreD \\
\end{planar}


% here are some references to the labels from the custom counter
Sometimes I want to reference something about itemC with a ref \ref{c}, but other times, I need to talk about itemA with a ref \ref{a} more.

\end{document}

这里的输出显示了标题行中的附加标签以及标签中的正确引用：

我怎样才能在标题列中隐藏这个标签，即防止它显示出来？

Answer 1

这是完整的 MWE，以防其他人遇到这个问题。它接管了这里正如评论中提到的，但对我来说，它只是在没有序言中重置计数器的行的情况下编译。如果您需要第二个重新开始计数的表，对我有用的是定义一个新的计数器。

\documentclass{article}
\title{MWE of Issue}
\author{me}

\usepackage{tabularx}

% define the counter
\newcounter{slots}
\def\rownumber{}
% define counter for other table
\newcounter{slotsb}
\def\rownumberb{}


\begin{document}
\maketitle

Some text here. 

% use the counter in a table with a header
\begin{tabular}{>{\rownumber}rlll} \gdef\rownumber{\refstepcounter{slots}(\theslots)}
    Pos.    & Type  & Elements  & Forms \\
    \label{a}     & itemA          & aboutA & moreA \\
    \label{b}     & itemB          & aboutB & moreB \\
    \label{c}     & itemC          & aboutC & moreC \\
    \label{d}     & itemD          & aboutD & moreD \\
\end{tabular}

% here are some references to the labels from the custom counter
Sometimes I want to reference something about itemC with a ref \ref{c}, but other times, I need to talk about itemA with a ref \ref{a} more.


% use the other counter in a new table with a header
\begin{tabular}{>{\rownumberb}rlll} \gdef\rownumberb{\refstepcounter{slotsb}(\theslotsb)}
    Pos.    & Type  & Elements  & Forms \\
    \label{d}     & itemD          & aboutD & moreD \\
    \label{e}     & itemE          & aboutE & moreE \\
\end{tabular}



\end{document}

输出如下：
