title: Tabulator: How to get a column of a column group?
body: <p>If you take a look at the first example at <a href="http://tabulator.info/examples/4.4#column-groups" rel="nofollow noreferrer">http://tabulator.info/examples/4.4#column-groups</a>, how do I get a reference to the column "Personal Info", so I can toggle/show/hide it?</p>
  
  <p>I tried it with <code>var col = table.getColumn("Personal Info")</code> but that did not work (as expected).</p>
  
  <p>I would prefer a vanilla JS solution which uses the built-in tabulator API. But jQuery is also ok as an alternative.</p>
  
  <p>Here is a jsfiddle <a href="https://jsfiddle.net/jmartsch/g7xewtf6/17/" rel="nofollow noreferrer">https://jsfiddle.net/jmartsch/g7xewtf6/17/</a></p>
  
  <p>I found out, that I can use <code>console.log(table.getColumn('gender').getParentColumn());</code>
  This does work, but it is not very elegant. It would be nice to have a solution that directly selects the column group header.</p>
