title: Automatic cell execution timing in jupyter lab
body: <p>In jupyter <strong>notebook</strong>, I can configure an automatic cell timing with <a href="https://github.com/ipython-contrib/jupyter_contrib_nbextensions" rel="noreferrer">nbextensions</a>, the result is like so:</p>

  <p>Obs.: I know that a similar result can be achieved with <code>%%time</code> magic, but I want it to be automatic, so I don't have to place the magic function at the beginning of each cell.</p>
