How can I.. ?

Hey, this framework is awesome!

How can I grow up the cell ? A2 is bigger than the cell

  $writer->writeSheetHeader('Sheet1', $header, $styles2, $col_options = ['widths'=>[50,20,30,40,50,60], 'suppress_row'=> 1] );
doesn't work

How can I add '%' ? ( nice to have but not important )

how can I add strings in a cell with a newliine ? ( \n doesn't work )

thank you very much!
