 clickableRows: $parent.clickableRows },
 bqMode: ['fieldValueOnly']">
 <!-- ko if: properties().limitmessage -->
 <div class="alert" data-bind="text: properties().limitmessage"></div>
 <!-- /ko -->
 <table class="table table-striped">
 <thead data-bind="if: header">
 <tr data-bind="foreach: header.children">

 </tr>
 </thead>
