Vertical rule with NiceTabular

Question

I’m trying to draw a vertical line with thickness 1pt with nicematrix package, but I obtain error compilation... any help is welcome. Here is my code

\documentclass{report}
\usepackage{nicematrix}
\begin{document}
\begin{center}
\NiceMatrixOptions{custom-line ={letter =I,width = 1 pt}}
\setlength{\arrayrulewidth}{1pt}
\begin{NiceTabular}{cIcc}
   $A$      & $1$   &    $2$        \ \hline
   $B$      & $3$   &    $3$

\end{NiceTabular}
\end{center}
\end{document}

Thanks. C.W

Hi, @Charly Watson, and welcome to TeX.SE. Are you receiving this error message: Package nicematrix Error: The key 'custom-line' is unknown for the command(nicematrix) \NiceMatrixOptions. }? — FHZ, Mar 30 '22 at 16:10
Hi @FHZ. Not exactly, my error message is the following:
‘NiceMatrix/RulesBis/width’ is unknown and is being ignored — Charly Watson, Mar 30 '22 at 16:32

The compilation error can be avoided using tikz to set the line in the custom-line I and the key line width.

The key total-width is then used to reserve the space for the new column/rule.

(with nicematrix.sty 2022/03/11 v6.8)

\documentclass{report}
\usepackage{nicematrix}
\usepackage{tikz}% added <<<<<<<<<<<<
\begin{document}
\begin{center}
\NiceMatrixOptions
{
    custom-line =
    {letter = I ,
    tikz = {line width=5pt, red },
    total-width=5pt 
    },  % changed <<<<<<
}
        \setlength{\arrayrulewidth}{1pt}
        \begin{NiceTabular}{cIcc}
            $A$      & $1$   &    $2$        \ \hline
            $B$      & $3$   &    $3$

        \end{NiceTabular}
\end{center}
\end{document}

From the commented code

The key total-width must be used only when the key tikz is used. When used, the key total-width specifies the width of the rule: it will be used to reserve space (in the preamble of the array or in the command for the horizontal rules).

+1 for letting explicit the need of version. I was working with version 5.13. Thanks. — FHZ, Mar 30 '22 at 17:51

I reproduce below some examples from CTAN -- nicematrix with a few alterations.

The command custom-line appears at

5.6 Commands for customized rules

where the given example starts with: \begin{NiceTabular}{lcIcIc}[custom-line = {letter=I, color=blue}] and in the sequence there is another example with TikZ and \NiceMatrixOptions. Unfortunately, both examples gave me the following error message: Package nicematrix Error: The key 'custom-line' is unknown for the(nicematrix) environment {NiceTabular}. ...cIc}[custom-line = {letter=I, color=blue}].

However, there is a way around. Sections:

5 The rules
- 5.2 The thickness and the color of the rules
- 5.3.2 The keys hvlines and hvlines-except-borders

present commands rules/color and rules/width, that might be useful, but are not exactly a new custom-line you may define for the whole document and use it where you want.

A MWE follows

\documentclass{article}
\usepackage{nicematrix}
\begin{document}
\begin{NiceTabular}{c|c|c}[rules/color=blue,rules/width=3pt]
  \hline
   rose  & tulipe &   lys    \
   arum  &  iris  & violette \
  muguet & dahlia &  souci   \
  \hline
\end{NiceTabular}
\setlength{\arrayrulewidth}{1pt}
\begin{NiceTabular}{cccc}[hvlines,rules/color=green!50!black,rules/width=4pt]
  rose & tulipe & marguerite & dahlia \
  violette & \Block[draw=red]{2-2}{\LARGE fleurs} & & souci \
  pervenche & & & lys \
  arum & iris & jacinthe & muguet
\end{NiceTabular}
\end{document}

I still may check how to define the new column line type globally, although I'm not an expert in this package. This answer is more a quick fix than a definite approach to the problem, or even an explanation why your problem appears. — FHZ, Mar 30 '22 at 16:38
Many thanks @FHZ. But I want only one vertical rule with different thickness... your solution give all rules (both vertical and horinzontal) with the same thickness (3pt and 4pt) — Charly Watson, Mar 30 '22 at 16:39
Indeed. I'm not sure, but you will probably have to use another solution or package. Check this for example. — FHZ, Mar 30 '22 at 16:43
And maybe you could edit your question presenting your need for defining multiples rule styles and using them along the document. — FHZ, Mar 30 '22 at 16:44

A small variation of the nice {Simon Dispa answer (+1):

\documentclass[border=3.14152, varwidth]{standalone}
\usepackage{nicematrix,tikz}
\usetikzlibrary{decorations.pathmorphing}
\NiceMatrixOptions
{custom-line = {letter = I,
                tikz = {},   % <---
                width = 2mm} % <---
}
\begin{document}
[
\setlength{\arrayrulewidth}{1pt}
\begin{NiceTabular}{cIcc}
   A      & 1   &    2        \ \hline
   B      & 3   &    3
\end{NiceTabular}
]
\end{document}

Some edit in your code:

\documentclass{report}
\usepackage{nicematrix}
\begin{document}
    \begin{center}
%   \NiceMatrixOptions{custom-line ={letter =I,width = 1 pt}}
        \setlength{\arrayrulewidth}{1pt}
        \begin{NiceTabular}{c|cc} %<-- changed
            $A$      & $1$   &    $2$        \ \hline
            $B$      & $3$   &    $3$

        \end{NiceTabular}
    \end{center}
\end{document}

It doesn't seem to answer OP's question. Package nicematrix presents a custom-line command with I as column separator. In your answer, you just removed letter I for the conventional column separator |. – FHZ Mar 30 '22 at 16:09
