title: SSRS alternate row colors with column groups
body: <p>I have reports in SSRS where I'm able to alternate the row colors using this expression:</p>
  
  <pre><code>=IIF(ROWNUMBER(NOTHING) MOD 2, "LightSteelBlue","WhiteSmoke")
  </code></pre>
  
  <p>This works great.  However, I have a report that has a column grouping, and this seems to mess up the alternating row colors.  </p>

  <p>The grouped columns will alternate column colors instead of row colors.  I've searched and found possible solutions with row groupings but nothing with column groupings, or at least nothing I can get to work.  I'm just trying to have every other row be "LightSteelBlue" or "WhiteSmoke," nothing fancy.</p>
  
  <p>Any ideas?</p>
