EDIT Like some comments below are remarking the table environment doesn't allow tables over more than one page. However the solution works fine
I need to make a table over more than one page. The standard approach seems to be to use the ltablex environment. However, it doesn't work; also I assume that the table environment may also be required for the thesis template I work on (e.g. suppose for the capture).
\documentclass[11pt]{article}
\usepackage{booktabs}
\usepackage{tabularx}
\usepackage{ltablex}
\begin{document}
\begin{table}
\caption{Example of an table}
\label{tab:daypack}
\begin{tabularx}{\linewidth}{@{}cX@{}}
\toprule
\textbf{Column 1} & \textbf{Column 2} \\[6pt]
\midrule
\endhead
