*Created originally on Bitbucket by [jesage (Jesage)](https://bitbucket.org/%7B15e7c34a-8824-4ea1-8098-a222029bef9a%7D/)*
wb = load_workbook(fname)
ws = wb.active
ws.delete_rows(1,5)
ws.append([1000])
ws.save(fname)
there will be some blank rows before the cell '1000'
it seems that _current_row variable is not updated after delete_rows
issue
