Slicer and Collapse Row on Pivot Table

Jan 25 at 9:19 PM
I have been using EPPlus to create a pivot table. So far, things are working great, but I have a few questions.
  1. Is there a way to add a Slicer to the worksheet?
  2. Also, is there a way to collapse a row in a pivot table? I have tried numerous ways to do this within EPPlus, but it seems like the pivot table isn't recognized until Excel has fully rendered.
Thanks!!
