title: LaTeX tabular multicolumn produces uneven cell widths
body: <p>Consider following LaTeX-Code:</p>
  
  <pre><code>\begin{tabular}{c|c|c|c|c|c|c|c|c}
      \hline
      \textbf{Bit $\rightarrow$} &amp; 7 &amp; 6 &amp; 5 &amp; 4 &amp; 3 &amp; 2 &amp; 1 &amp; 0\\
      \hline
      Byte 1 &amp; \multicolumn{4}{c|}{MQTT Control Packet type} &amp; \multicolumn{4}{c}{Flags specific to each MQTT Control Packet type}\\
      \hline
      Byte 2 &amp; \multicolumn{8}{c}{Remaining Length}\\
      \hline
  \end{tabular}
  </code></pre>
  
  <p>Why does it look like this? I want the cells on the first row to have the same width!</p>
