title: SSRS: Can't remove whitespace when hiding Tablixes or Rectangles
body: <p>I am creating a report which contains tables at the top and bottom that are always visible. However, between these are 12 tablixes which optionally appear based on the existence of data for them. When they do not exist there is a considerable amount of whitespace in the middle section of the report which makes the report look awful.</p>
  
  <p>I've tried two strategies to fix this:</p>
  
  <ol>
  <li><p>Set up one rectangle to hold all tablixes. Set all tablixes to have the hidden property set to be true if CountRows() &lt; 1. Leave no gaps in between the tablixes so as to not leave cumulative gaps. </p></li>
  <li><p>Set up one rectangle per tablix. Set all rectangles and all tablixes to have the hidden property set to be true if CountRows(dataset for tablix) &lt; 1. Leave no gaps in between the rectangles so as to not leave cumulative gaps. </p></li>
  </ol>
  
  <p>I can think of no other setting to rid the report of gaps for hidden tables.</p>
