title: Uncollapse Columns by RowClick
body: <p>I have setup my table in Tabulator with <code>responsiveLayout:&quot;collapse&quot;</code> and <code>responsiveLayoutCollapseStartOpen:false</code>.</p>
  <p>My table display properly with collapsed columns.
  I added <code>formatter:&quot;responsiveCollapse&quot;</code> as column and I properly get the column with + and - icons and can manually expand/collapse the columns.</p>
  <p>But for usability on a smartphone, the icon renders really a bit small.
  I want to add to expand/collapse based on callback <code>rowClick</code>.</p>
  <p>I found <code>responsiveCollapse</code> and <code>toggleList</code> in tabulator.js, so I think I know what needs to happen. However I am totally struggling how to return it out of <code>rowClick</code>.</p>
  <p>Thank you very much for a hint in advance.</p>
  <p>In the tabulator constructor I have:</p>
  <pre class="lang-js prettyprint-override"><code>columns:[ 
      { formatter:&quot;responsiveCollapse&quot;, width:30, minWidth:30,      
      hozAlign:&quot;center&quot;, resizable:false, headerSort:false, responsive:0 },           
      { title:&quot;Ren.&quot;, field:&quot;Race_Number&quot;, sorter:&quot;number&quot;, 
      hozAlign:&quot;center&quot;, minWidth:60, widthGrow:1, responsive:0 },
  ]
  </code></pre>
  <p>And basically I want to achieve the some functionality as formatter:&quot;responsiveCollapse&quot; in rowClick:</p>
  <pre class="lang-js prettyprint-override"><code>rowClick:function(e, id, data, row){ 
      //trigger an alert message when the row is clicked
      //what to do here to achieve same as formatter:&quot;responsiveCollapse&quot;
  },
  </code></pre>
