title: Tabulator: reformat cell on 'cellEdited' event
body: <p>I am new at using Tabulator.js but I am willing to learn and use it deeply. I was indeed looking for a good tableGenerator library for a main project. So far, it seems to be pretty nice.
  I am currently using a CND link for version 5.0.7.</p>
  <p>Now here is my problem: I try to format cell with a <code>background-color</code> depending on the cell value (the cell name is status and the value can be either <code>true</code> or <code>false</code>). It works at the creation of the table. But it doesn't work if I change the cell value afterwards.</p>
  <p>I created a method called <code>statusFormatter</code>:</p>
  <pre class="lang-js prettyprint-override"><code>statusFormatter: (cell) =&gt; {
  
          if (cell.getValue() == true) {
              cell.getElement().style.backgroundColor = &quot;#A6A6DF&quot;;
          }
  
          return cell.getValue();
  },
  </code></pre>
  <p>I call this method on the <code>cellEdited</code> event:</p>
  <pre class="lang-js prettyprint-override"><code>mainTable.on(&quot;cellEdited&quot;, function (cell) {
      clientTabulator.statusFormatter(cell);
  });
  </code></pre>
  <p>I suppose there is something wrong with the return in the method. But I don't know what to return when it is the style that I need.</p>
  <p>Hope someone can help...</p>
