# Alignment of contents similar to tabular in a multicol environment

I have placed a multicol environment in the middle of a page with 3 columns as you can see in the followning image:

In each column I want the contents to be aligned one under the other as if there were a tabular environment. I say as if there were bacause I tried using a tabular but it didn't break in the 3 columns. So what is the correct way to do this?

A MWE with my current code is this:

\documentclass[12pt]{article}
\usepackage[top=0.7in, bottom=1.2in, left=0.8in, right=0.8in]{geometry}

\setlength{\parindent}{0cm}

\usepackage[fleqn]{amsmath}
\usepackage{unicode-math}

\usepackage{multicol}

\newcommand{\3}{\vspace{0.3cm}}

\begin{document}

\begin{multicols}{3}

\3

\3

\3

\3

\3

\3

\3

\3

\3

\3

\3

\3

\3

\3

\3

\end{multicols}

\end{document}
