How do I use tabela.xls as a data source to a LaTeX table or even a table made with TikZ with the following command?
Note: I wanted to use tabela.xls as a data source for multiple files. Tex and that it is synchronized when I change the tabela.xls.

```
\documentclass[a4paper]{article}
\usepackage{tikz}
\usetikzlibrary{matrix}
\begin{document}
  \begin{tikzpicture}
    \matrix[matrix of nodes,nodes={minimum width=1.5cm}] at (0,0)
      {
    1 & Knuth &         10\\
    2 & Lamport &  10\\
    3 & Mittelbach & 7\\
    4 & Oetiker &   7\\
      };
  \end{tikzpicture}
\end{document}

```
