title: Rules for formatting the border of cells in a grouped tablix report
body: <p>Does anyone know if there are rules dictating the order of the rendering of formatting of the borders of cells in a grouped tablix report?</p>
  
  <p>I have a group - the formatting of the cells is behaving unpredictably and I'm guessing that there is an order that RS applies to it's formatting i.e if I've highlighted the whole group row and applied formatting X it will be applied either before or after the formatting I've applied on a single cell of that row?</p>
