[Tex/LaTex] Author information column wise

Question

I am using authblk package and I want to achieve following output using this package.

Answer 1

I don't think you need the authblk package to achieve the desired look.

\documentclass{article}
\title{Author Practice}
\author{%
\begin{tabular}{c} Author 1 \\ University \\ Email-id \end{tabular} \and
\begin{tabular}{c} Author 2 \\ University \\ Email-id \end{tabular} \and
\begin{tabular}{c} Author 3 \\ University \\ Email-id \end{tabular} \and
\begin{tabular}{c} Author 4 \\ University \\ Email-id \end{tabular} }
\date{}
\begin{document}
\maketitle
\end{document}

Here's a different look, prompted by the OP's (now-deleted) comments.

\documentclass{article}
\title{Author Practice}
\author{%
\begin{tabular}{c} Author 1 \\ University1 \\ Mail1 \\ \\
Author 3 \\ University3 \\ Mail3 \end{tabular} \and
\begin{tabular}{c} Author 2 \\ University2 \\ Mail2 \\ \\
Author 4 \\ University4 \\ Mail4\\
\end{tabular} }
\date{}
\begin{document}
\maketitle
\end{document}
