Counter manipulation within table

[JiriSrubar]

The code

\newcounter{ca}
\arabic{ca}

\begin{tblr}{hlines,vlines}
	\stepcounter{ca}\arabic{ca}	&
	\stepcounter{ca}\arabic{ca}	&
	\stepcounter{ca}\arabic{ca}	
\end{tblr}

\arabic{ca}

results in

I would expect another numbers ...

Am I missing something?

To build a nice table, tabularray need to measure every cells several times, therefore the counters inside the cell will be increased several times.

If the value of cells are related to rownum or colnum, you may use these counters directly. Otherwise you could build the table body first and save it in a macro, then use expand option to expand the body macro.

\documentclass{article}

\usepackage{tabularray}

\begin{document}

\section{First Method}

\begin{tblr}{hlines,vlines}
  \arabic{colnum} & \arabic{colnum} & \arabic{colnum}
\end{tblr}

\section{Second Method}

\ExplSyntaxOn
\tl_clear:N \mybody
\int_step_inline:nn {3} {
  \int_compare:nNnTF {#1} = {3} {
    \tl_put_right:Nn \mybody { #1 }
  }{
    \tl_put_right:Nn \mybody { #1 & }
  }
}
\ExplSyntaxOff

\begin{tblr}[expand=\mybody]{hlines,vlines}
  \mybody
\end{tblr}

\end{document}

Thanks for explanation and for suggested workarounds, I will try them.

However ... i think, that simple counter manipulation - even within table - is quite essential ...

[lvjr]

I have created issue #89.

[lvjr]

This bug has been fixed. Just add \UseTblrLibrary{counter} to your code with the latest package file:
https://github.com/lvjr/tabularray/raw/main/tabularray.sty

I'm not totally sure it's a good idea but tabularx saves the value of all latex counters (using the mechanism set up for \include) and resets them for each trial.

 \def\@elt##1{\global\value{##1}\the\value{##1}\relax}%
  \edef\TX@ckpt{\cl@@ckpt}%

[lvjr]

Tabularray measures every cell multiple times in one trial run. How about redefining \setcounter command and only saving the value of counters used in cells? Should not be a default behavior; better as a library.

[lvjr]

Maybe it is better to define a new command \SetCounter based on \setcounter, and advise users to use the new command.

[FrankMittelbach]

please don't invent commands like \SetCounter for this case. The problem is that all counters used within the table needs resetting and it would be impossible for a user to know which are going to be used as they may well be hidden inside a command they use instead of being explicit. What might be faster then resetting all, could be to detect which are used in the first pass and reset only them, but that could and should be done automatically in my opinion.

[lvjr]

Thank you. I still have some confusion:

1. How could I detect which counters are used without hooking or modifying \setcounter command?
2. To reset counters, I need to use several private macros. But it is always not a good practice to use them. Could LaTeX kernel provide some public macros for doing this?

[FrankMittelbach]

@lvjr you couldn't I guess. My remark was more on the general approach: there could and probably should a general mechanism for this used by various environments that reprocess their data several times. It would require on the first pass that \setcounter and probably other commands that alter state to be changed so that they record the state to return to. On the following passes they would then use their normal definition and at the start of each pass the collected information would be used to do a reset. I'm clearly handwaving here, but it is probably faster than recording the state ofr all counters and resetting all of them, but right now it can only be done by locally changing the setters.

问题如下：

1. 使用了自定义\cs{xuhao}命令，本来是解决tabular或longtable表格中，自动计数的问题。
2. 新增counter这个Library之前，计数器并不正确
3. 在使用counter之后，计数器可以计数正确。但是表格行间距会撑的比较开，而且Q或者colspec等设置行、列居中格式等，似乎并不能很好的完成工作

• 使用counter后截图：
  

• 直接手动输入序号截图：
