# Need labels and refs in longtable rows [duplicate]

This question already has an answer here:

In a longtable, I need the first column to display numbers based on an enumeration by references to labels. This means I can refer to the rows somewhere else in the text.

I imagined it would help to create a label and reference to that label in the same cell, but I keep getting 1-figures instead of an incrementing number.

Here's an example of what I have:

\documentclass[a4paper]{article}
\usepackage{longtable}
\begin{document}

\begin{longtable}{|l|l|}

\hline
\textbf{Number} & \textbf{Title} \\
\hline
\endfirsthead

\label{row:thefirst}
\ref{row:thefirst} &
First \\
\hline

\label{row:thesecond}
\ref{row:thesecond} &
Second \\
\hline

\label{row:thethird}
\ref{row:thethird} &
Third \\
\hline

\end{longtable}

\end{document}


I have tried changing the "row:" to something like "itm:" or "fig:", but nothing helps.

Perhaps, I need to put it in some context like when using \begin{figure}, but I am not sure how that would turn out when in a table cell.

Any suggestions? Thanks!

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

• The "row:" is just a name you define. The funcionality isn't touched by this definition. (That's the reason why it did not help.) – Ruben Dec 20 '13 at 13:21
• Alright, but then what should I do to get to the numbers working...? – Gerard Nijboer Dec 20 '13 at 13:30

• \label always refers to the last counter stepped with \refstepcounter (or actually whatever counter is saved in \@currentlabel), independently from the label name you choose. In your case it is the table counter as \begin{longtable} does \refstepcounter{table} internally. You need some counter that is stepped every row if you want to be able to refer to the rows. – clemens Dec 20 '13 at 15:13

The form of the label string has no effect whatsoever: it is an arbitrary internal string for cross referencing. You need to increment a counter if you want to count something.

\documentclass[a4paper]{article}
\usepackage{longtable,array}
\newcounter{ltrow}
\begin{document}

\setcounter{ltrow}{0}
\begin{longtable}{|>{\refstepcounter{ltrow}\theltrow}l|l|}

\hline
\multicolumn{1}{|l|}{\textbf{Number}} & \textbf{Title} \\
\hline
\endfirsthead

\label{row:thefirst}
&
First \\
\hline

\label{row:thesecond}
&
Second xxx\\
\hline

\label{row:thethird} &
Third \\
\hline

\end{longtable}

xxx is on row \ref{row:thesecond}
\end{document}
