body: <p>I need to create the following table in LaTeX and I just cannot seem to get it right. </p>

  <p>The text inside the cells is not centered correctly and the same goes for the "Eye movements" cell. Could any of you see what I doing wrong?</p>
  
  <pre><code>\begin{tabular}{ccc|c}
  &amp; &amp; \multicolumn{2}{c}{\textbf{Response}} \\ 
  &amp; &amp; unnatural &amp; natural \\ \cline{3-4}
  \multicolumn{1}{c}{\multirow{2}{*}{\begin{sideways}\textbf{Eye movement}\end{sideways}}} &amp;
  \multicolumn{1}{c|}{\begin{sideways}unnatural\end{sideways}} &amp; 1 &amp; \multicolumn{1}{c|}{2} \\ \cline{2-4}
  \multicolumn{1}{c}{}                        &amp;
  \multicolumn{1}{c|}{\begin{sideways}natural\end{sideways}} &amp; 3 &amp; \multicolumn{1}{c|}{4}   \\ \cline{3-4}
  \end{tabular}
