# how to create columns of array

I use the following code to generate this:

\begin{center}
2 Iteración\\
Fila $S_{1}$
\end{center}
\small
$\begin{array}{crl} \kbordermatrix{\mbox{ }& & & & & & & \\ Fila Vieja & 0 & 2 & 1 & 1 & 0 & 0 &18 \\ C. Pivote & 2 & 2 & 2 & 2 & 2 & 2 &2\\ Nueva F. Pivote & 0 & 1 & 1/3 & 0 & 0 & 1/3 & 8 \\\cline{2-8} Nueva Fila & 0 & 0 & 1/3 & 1 & 0 & -2/3 & 2 \\ } \end{array}$

\begin{center}
Fila $S_{2}$
\end{center}
\small
$\begin{array}{crl} \kbordermatrix{\mbox{ }& & & & & & & \\ Fila Vieja & 0 & 2 & 3 & 0 & 1 & 0 & 42 \\ C. Pivote & 2 & 2 & 2 & 2 & 2 & 2 &2\\ Nueva F. Pivote & 0 & 1 & 1/3 & 0 & 0 & 1/3 & 8 \\\cline{2-8} Nueva Fila & 0 & 0 & 7/3 & 0 & 1 & -2/3 & 26 \\ } \end{array}$
\begin{center}
Fila $Z$
\end{center}
\small
$\begin{array}{crl} \kbordermatrix{\mbox{ }& & & & & & & \\ Fila Vieja & 1 & -3 & -2 & 0 & 0 & 0 & 0 \\ C. Pivote & -3 & -3 & -3 & -3 & -3 & -3 & -3\\ Nueva F. Pivote & 0 & 1 & 1/3 & 0 & 0 & 1/3 & 8 \\\cline{2-8} Nueva Fila & 1 & 0 & -1 & 0 & 0 & 1 & 24 \\ } \end{array}$


My question is how could I do this in multiple columns?

I'm sorry, I'm having some exercises the simplex method to latex, but I see that you are spreading far, so I started to investigate how to place this in 3 columns thing I could not do.

Example

There is the multicol package which helps you put anything you like in two (or more) columns. E.g.
...

You can use \columnbreak if you want to break your text manually.
