How to expand/collapse pivot tables in mashup

[ruben_moya]

Dear experts,

Is there a reason why the option expand /collapse doesn't appear when calling a pivot table objetct in mashup?

It automatically generates the expand or export option, but couldn't find expand/collapse:

<div uib-tooltip-popup="" uib-title="" content="Export" origin-scope="origScope" class="tooltip ng-scope ng-isolate-scope top fade in" tooltip-animation-class="fade" uib-tooltip-classes="" ng-class="{ in: isOpen }" style="top: -33px; left: -14px;"><div class="tooltip-arrow"></div><div class="tooltip-inner ng-binding" ng-bind="content">Export</div></div>

Someone already ask the same question but got no answers:
