title: Pivot Table show only rows with values in range
body: <p>I have a CSV report that has fields Date, User, and Bandwidth for 1000 users per day over 30 days (30,000 lines).  I loaded these into a pivot table so Date was the Cols, User was the rows, and bandwidth is value as "Rank of total column value".</p>
  
  <p>I'd like to filter the table such that it only shows users who have at least 1 top 50 (1-50) in the 30 day range.</p>
  
  <p>I've tried using the filter options for rows and columns, but I can't seem to perform this filter.  Anyone have any ideas?</p>
