title: Sorting day of week columns in tablix report chronologically
body: <p>I have an SSRS tablix report with the day of the week as columns. SSRS sorts these colums alphabetically (Friday, Monday, Saturday, Sunday, Thursday, Tuesday, Wednesday) but I want them sorted chronologically (Sunday, Monday, ..., Saturday).</p>
  
  <p>I have two columns in my dataset named DOW (values 1, 2, ..., 7) and DayName (values Sunday, Monday, ..., Saturday).</p>
  
  <p>I have my Sorting with DOW as the major sort both in my Dataset and in my Tablix Properties.</p>
  
  <p>I even tried concatenating DOW to DayName but it still displays as 6-Friday, 1-Monday, etc.</p>
  
  <p>How do I get the column headings to display as Sunday, Monday, ..., Saturday?</p>
