我需要在xlwt

Question

默认表：

在我的脚本操作之后，我想得到这个

rb = xlrd.open_workbook('example.xls', formatting_info=True)
wb = copy(rb)
sheet = wb.get_sheet(0)
...?
wb.save('example.xls')

使用openpyxl的解决方案：

def insert_rows(ws, row_idx, cnt, above=False, copy_style=True, copy_merged_columns=True, copy_data=True):
    """Inserts new (empty) rows into worksheet at specified row index.

    :param row_idx: Row index specifying where to insert new rows.
    :param cnt: Number of rows to insert.
    :param above: Set True to insert rows above specified row index.
    :param copy_style: Set True if new rows should copy style of immediately above row.
    :param copy_data: Set True if new rows should take on data or formula from immediately above row, filled with references new to rows. (changed from formulae only by Hillel)

    Usage:

    * insert_rows(2, 10, above=True, copy_style=False)
