Combination (mix) of enumerate and tabular environments with labels giving the number from the enumerate environment

Question

I'm trying to do something similar to How can I mix itemize and tabular environments?.

However, I'm trying to use an enumerate environment, I want the items lined up like in a tabular environment, and I would like to reference the items in the enumerate environment using labels so that the references appear as the numbers in the enumerate environment.

Conceptually, the idea is like that of a bibliography style environment, but each item is a line in an enumerate environment. Conceptually, the layout would look something like this, but with the header and the lines in the body lining up, of course.

\documentclass{article}
\begin{document}
\newcommand{\corr}[4]{%
\begin{tabular}{llll}
%Date & From & To\\
#1 & #2 & #3 & #4
\end{tabular}
}

\section{List of Correspondence}

\begin{tabular}{llll}
\textbf{Date} & \textbf{From} & \textbf{To} & \textbf{Summary}\\
\end{tabular}
\begin{enumerate}
\item\label{c1} \corr{September 26th 2011}{Sender1}{Recepient1}{Some stuff}
\item\label{c2} \corr{September 23rd 2013}{Sender2}{Recepient2}{Some other stuff}
\end{enumerate}

Here is \ref{c1} and \ref{c2}.

\end{document}

ADDENDUM: The multienum package does something close to what I want, except that I don't see how to include the headers.

ADDENDUM2: If there was some way to directly reference the itemize counter without the overhead of placing labels, that would be helpful.

Answer 1

Here is a solution, if I've well understood your requirements:

\documentclass[11pt, a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern} 
\usepackage{array}
\newcommand{\colhead}[1]{\multicolumn{1}{>{\bfseries}l}{#1}}
\newcounter{tabenum}\setcounter{tabenum}{0}
\newcommand{\nextnum}{\refstepcounter{tabenum}\thetabenum.}

\begin{document}
\section{Examples}
Here is an example:

\begin{center}
   \begin{tabular}{>{\nextnum}l@{\hspace{\labelsep}}*{3}{l@{\quad\quad}}l}
      \colhead{} &  \colhead{Date} &  \colhead{From}  & \colhead{To}  & \colhead  {Summary} \\
   \hline
      \label{sep11} &  September 26\textsuperscript{th} 2011 & Sender 1 &Recipient 1  \\
      \label{sep13} & September 23\textsuperscript{rd} 2013 & Sender 2 & Recipient 2
   \end{tabular}
\end{center}

According to case \ref{sep13}, Sender 2 sent a letter to Recipient 2.
