title: PhpExcel - How insert the same row after row N?
body: <p>I have php template. this is a empty table (T0 rows) with some footer at the bottom.
  From php i try to fill the table, but if i had T1 rows (T1 > T0) then trouble appers.</p>
  
  <p>I beleve that empty table should contains one empty row. And we know this row number.
  Then we copy this row (insert the same rows) T1 times and fill empty table. Footer goes down. And everything will be ok </p>
  
  <p>Give me an example, how i can do this. Thank you.</p>
