title: Tabulator Selectable and rowSelection column definition
body: <p>I am using Tabulator and want to allow the end-user to only select one row.  I used the Selectable:1 property without issue.  However, visually I want to show the user which row since the current select row highlight is insufficient, so I decided to see if I could add a checkmark to confirm that a specific row is indeed selected.  Reviewing the documentation shows a formatter called &quot;rowSelection&quot;.  I added this and it works.  However, the header of the rowSelection column has a checkbox (assuming for select all/deselect all), which is enabled.  Is there any way to disable this since the end user can only select one row in this case?  The workflow is that the user selects a table row and clicks on the View Only, Update or Delete buttons already in place outside of Tabulator.</p>
  <pre class="lang-js prettyprint-override"><code>columns:[   // define the table columns
      {formatter:&quot;rowSelection&quot;, titleFormatter:&quot;rowSelection&quot;, align:&quot;center&quot;, headerSort:false},
      {title:&quot;Period&quot;, field:&quot;submissionPeriod&quot;},
      //...
  ],
  </code></pre>

  <p>And just an FYI, the header Checkmark is not Center aligned (it is left aligned).</p>
