title: SSRS 2008 Hidden Columns Should NOT Export to CSV
body: <p>When I hide columns in SSRS they still appear in the CSV export.</p>
  
  <p>I have to hide columns, not the entire tablix. </p>
  
  <p>This is what I have tried already:
  The filters in the tablix hide rows not columns.
  The DataElementOutput per column can not be set using an expression.</p>
