title: 'Freeze first column' half transparent in Power BI Report Builder
body: <p>When building a table in Power BI report builder I need to 'freeze' the first column. I have done this using tablix properties and ticking 'Keep header visible while scrolling'. I have also made the tablix background white rather than 'No Color'.</p>
  
  <p>This works great when I run the report in Report Builder. I then publish the report to web service and it half works...</p>
  
  <p>The top half of the table works great but as you scroll down and across the first column becomes transparent?!</p>
  
  <p>Any tips/ideas as to why this is happening and how to fix it?</p>
