I am trying to build a long table that extends to multiple pages and I don't want vertical lines in the table but there are different sections within the table divided by horizontal lines. I am using the long table package but no success. I am providing the codes that I am using below:
\usepackage{longtable}
\begin{document}
\begin{longtable}[ \centering

\multicolumn{3}{|r|}{{Continued on next page}} \\
