title: Latex: issue with Multirow
body: <p>I'm using the multirow package to have multiple elements in the same row.</p>
  <pre><code>\begin{table}[!h]
  \centering
  \resizebox{1.0\textwidth}{!}{%
      \begin{tabular}{l*{4}{c}|cc|c}
                &amp; \mathcal{D} &amp; $\rho$ &amp; $N_c$ &amp; $N_C^{inv}$ &amp; $C$ &amp; $C^{inv}$ &amp; $Q$\\
      \hline
      \multirow{2}{*}{Mod0} &amp; \num{9.99} &amp; \num{1.36e+1} &amp; \num{3.32} &amp; \num{7.05e+1} &amp; \num{4.69e-3} &amp; \num{6.59e-2} &amp; \num{1} \\
      &amp; \num{-9.10} &amp; \num{3.69e-1} &amp; \num{-1.70e+1} &amp; \num{-6.36e-2} &amp; &amp; &amp;\num{1} \\ \hline
      Mod1 &amp; \num{1.94e+1} &amp; \num{1.60e+1} &amp; \num{8.65e+1} &amp; \num{1.86e+2} &amp; \num{} \\
      \end{tabular}%
  }
  \end{table}
  </code></pre>
  <p>For the columns C and C^{inv} there is just one element (instead of two) and therefore I would like the single element to be in the centre of the line and not in the upper side. How can I do that?</p>
