Since the "workbook.columns[0].width" exists when exporting to Excel AND that the mix of cell.colSpan and cell.wrap doesn't change the row height automatically when the text wrap (it only works when colSpan = 1) I'd like the ability to change the row height manually : rows[0].height = 50 Of course the best implementation for us would be the automatic row height calculation when text wrap with colSpan > 1. Thank you !
