It's my first time utilizing latex, and I can’t get rid of this problem.
im doing an article with two columns, using
\begin{multicols}{2} but the problem, is that when I put a table with \begin{tabular} the text inside its really big, so, the text cross the to the other column of the article and it superpose the text of the second column. I would really appreciate the help.
thank you!

\documentclass{...}, the required\usepackage's,\begin{document}, and\end{document}. That may seem tedious to you, but think of the extra work it represents for TeX.SX users willing to give you a hand. Help them help you: remove that one hurdle between you and a solution to your problem. – Astrinus Jun 03 '15 at 15:25{cccc}for 4 columns that do not allow lin ebreaking, you probably want{p{1cm}p{1cm}p{1cm}p{1cm}}for 4 1cm wide columns (or whatever size you need) – David Carlisle Jun 03 '15 at 15:27table*environment to encase thetabularmaterial? Atable*enviroment spans both text columns. – Mico Jun 03 '15 at 16:19
