title: How to detect if a table has rows in crystal 2008
body: <p>Is there a built in crystal method to detect whether the a table in a crystal report has any rows?</p>
  
  <p>I have created a sub report which has some Title text in the header and a detail line with the table info.</p>
  
  <p>I want to be able to supress the title text from printing if there is nothing to print.</p>
  
  <p>Also, is there any way to pass this to the "master" report so that I can suppress printing the sub report completely if there is nothing to print?</p>
  
  <p>Regards</p>
