title: Merge cells in Table (RDLC)
body: <p>Can I get merged cells in some rows while other rows cells remain not merged? Like this way:</p>
  
  <pre><code>| group row 1 |
  | cell1 | cell3 | cell4 | cell5 | cell6| 
  | cell1 | cell3 | cell4 | cell5 | cell6|
  ...
  | group row 2  |
  ...
  </code></pre>
  
  <p>I have to export to Excel content of datagridview with group rows and it would be nice to get something like that. I've tried to use ColSpan element in TableCell but it affects all rows.</p>
