You have to load multirow. As the table overflowed into the margin, I added the geometry package, to have more sensible margins, and systematically used the siunitx package to have a thin unbreakable space between number and unit. Here is a simple code:

\documentclass[12pt,a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage{geometry} 
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{multicol}% Agrupamento de colunas em tabelas
\usepackage{array, multirow, caption}
\usepackage{pgfplots}
\usepackage{float}
\usepackage{siunitx}
\sisetup{copy-decimal-marker}

\begin{document}

\begin{table}[h]
\centering\setlength\extrarowheight{2pt}
\caption{}
\begin{tabular}{|c|l|c|}
\hline
\multirow{2}{*}{Comportamento elástico}&{Coeficiente de Poisson, $\nu$} & 0,42 \\ \cline{ 2- 3}
 & Módulo de elasticidade, E & \SI{1730}{\MPa} \\ \hline
\multirow{5}{*}{Comportamento plástico} & & \ang{38,5}\\ \cline{ 2- 3}
 & Ângulo de fluxo interno, $\beta$ & \ang{38,5} \\ \cline{ 2- 3}
 & Rácio de fluxo interno, K & 1 \\ \cline{ 2-3}
 & Tensão de rotura à tração, $\sigma_{ut}$ & \SI{32,6}{\MPa} \\ \cline{ 2- 3}
 & Tensão de rotura à compressão, $\sigma_{uc}$ & \SI{56,3}{\MPa} \\ \hline
\end{tabular}
\end{table}

\end{document}

  • Bernard, i used the calc2latex macro. thank you for your code, but i have another problem , i want to center the values of the third column, can you fix it? thanks! – Paulo B. Oct 12 '16 at 12:50
  • @Paulo B: you just have to use the ccolumn specifier. In my updated answer, I also use the \SI command to get a correct spacing between number and unit (\,). B.t.w., your comment in the preamble: % Agrupamento de colunas em tabelas seems to mean loading multicol is to merge columns in tables (I don't speak portuguese, but it's a Latin language…). If my interpretation is correct, it's wrong: multicol is to type part of a document in two (or more) columns. – Bernard Oct 12 '16 at 14:28
  • Bernard, thank you for all the corrections. is it possible put the words '' Drucker-Prager'' in the first column? like the image : – Paulo B. Oct 13 '16 at 12:56
