title: How to set CSS class/style to particular column in GridX?
body: <p>I would like to set the custom style or CSS class on the column of Dojo's <strong>GridX</strong> to customize the content layout (centering of text, background color, font etc.).</p>
  
  <p>For example, I have now the following block (rendered):</p>
  
  <pre><code>&lt;td colid="extern" tabindex="-1" role="gridcell" class="gridxCell  " aria-describedby="gridx_Grid_0-extern"&gt;
      &lt;div class="gridxCellWidget" id="dijit__WidgetsInTemplateMixin_10" widgetid="dijit__WidgetsInTemplateMixin_10"&gt;
      &lt;/div&gt;
  &lt;/td&gt;
  </code></pre>
  
  <p>I'd like to tell GridX renderer to append the class <code>extern</code> to either <code>td</code> or <code>div</code> (or both).</p>
  
  <p>Is there a standard way to do so (a parameter to structure, for example)? If no, in which code fragment I could build my custom hook, that would do namely what I have described?</p>
