title: Expand Child Rows of Responsive Datatables automatically
body: <p>I have a responsive dataTable (<a href="https://datatables.net/extensions/responsive/" rel="nofollow">Responsive doc.</a>) in the following format: </p>
  
  <pre><code>var dataTableInfo = j$('[id$="dataTableInfo"]').DataTable({
                   responsive: {
                      "autoWidth": true,
                      details: {
                          type: 'column',
                          target: 0
                      }
                  },
                  columnDefs: [ {
                      className: 'control',
                      orderable: false,
                      targets:   0
                  } ]
              });
  </code></pre>
  
  <p>I fill this with data through a search to an external data source and I then have a second table inside the DataTable with additional data (in a child Row) that comes automatically from my instaniation. I can click on the icon in the first column to expand and show the child row, everything works fine. </p>
  
  <p>What I want to accomplish is to automatically expand the child rows through Javascript of this DataTable, once all the data has been loaded (I know when this occurs in a callback function). </p>
  
  <p>I have tried multiple variation of the following: </p>
  
  <pre><code>function ExpandTable(){
          var tab = j$('[id$="dataTableInfo"]').DataTable();
          alert(tab);
  
          tab.rows().every( function () {
  
              this.child.show();
  
          } );
      }
  </code></pre>
  
  <p>But my table simply won't expand its child rows. Nothing happens and no error messages in the console. </p>
  
  <p>Can anyone help me in explaining how I for example can simulate a button click according to this: </p>
  
  <pre><code>$('#example tbody').on( 'click', 'tr', function () {
  var child = table.row( this ).child;
  
  if ( child.isShown() ) {
      child.hide();
  }
  else {
      child.show();
  }} );
  </code></pre>
  
  <p>or in any other way automating this expanding of the child rows. </p>
  
  <p>Ciao! </p>
