Generate a continuosly numbered reference to e.g. a requirement

Question

I want to create a table with requirements for a project.

   \begin{table}[H]
      \centering
      \begin{tabularx}{\textwidth}{C{0.1}L{0.75}C{0.15}}
         \toprule
            \textbf{R\hyp{}ID} & \textbf{Requirement Description} & \textbf{Priority} \\
         \midrule
            R1 & Requirement 1 & 1 \\
            R2 & Requirement 2 & 1 \\
         \bottomrule
      \end{tabularx}
      \caption{Ziele}
      \label{tab:goals}
   \end{table}

What I wish to do now is, that the R1, R2 are labelled and can be referenced from the text with e.g. \cref{requirement-1}.

The command to create the R1 / R2 entries should be customizable: \uniqueReference{requirement}{R} where requirement would be the label prefix and R the text prefix.

   \begin{table}[H]
      \centering
      \begin{tabularx}{\textwidth}{C{0.1}L{0.75}C{0.15}}
         \toprule
            \textbf{R\hyp{}ID} & \textbf{Requirement Description} & \textbf{Priority} \\
         \midrule
            \uniqueReference{requirement}{R} & Requirement 1 & 1 \\
            \uniqueReference{requirement}{R} & Requirement 2 & 1 \\
         \bottomrule
      \end{tabularx}
      \caption{Ziele}
      \label{tab:goals}
   \end{table}

Is there a package which does this already? Or would I have to create a custom command?

I have found an answer.

First, check this question about Reference table row in LaTeX.

user31729 used a counter for both rows and cols. If you want a global unique ref counting, just remove the resetting mechanism at each start of environment aka \AtBeginEnvironment{tabular}{\setcounter{rowcntr}{0}}

You then could just define a new counter, such as:

\newcounter{rowcntr}
\renewcommand{\therowcntr}{\arabic{rowcntr}}
% A new columntype to apply automatic stepping
\newcolumntype{N}{>{\refstepcounter{rowcntr}}c}

I hope this accomplishes what you wanted to do. Here is the MWE code:

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{graphicx}
\usepackage[danish]{babel}
\usepackage{lscape}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage[usenames,dvipsnames,svgnames,table]{xcolor}
\usepackage{float} 
\usepackage{array}
\usepackage[top=2.81cm, bottom=2.75cm,right=2cm, left=2cm]{geometry}
\usepackage{etoolbox}
\usepackage{setspace}
\onehalfspacing
\usepackage{url}
\usepackage[hidelinks]{hyperref}
\hypersetup{breaklinks=true}
\newcounter{rowcntr}
\renewcommand{\therowcntr}{\arabic{rowcntr}}
% A new columntype to apply automatic stepping
\newcolumntype{N}{>{\refstepcounter{rowcntr}}c}
% Reset the rowcntr counter at each new tabular
%\AtBeginEnvironment{tabular}{\setcounter{rowcntr}{-1}}
\begin{document}
\begin{table}[H]
    \centering
    \caption{Table with questions} \label{tab:Q1}

        \label{que:whyisit}           B    &amp; Why is it you think ...          &amp; This is a good question      \\
        \label{que:doyouthink}        A    &amp; Do you think  ...                &amp; This Is also a good question \\
        \label{que:isitcorrect}       B    &amp; is it correct that you think ... &amp; This is question             \\ \hline
