Use openpyxl library, batch merge cells encounter problems

from openpyxl import Workbook
from openpyxl import load_workbook
from openpyxl.styles import NamedStyle, Border, Side, Alignment


# 创建一个工作薄
wb = Workbook()

# 创建一个工作表(注意是一个属性)
table = wb.active

# excel创建的工作表名默认为sheet1,一下代码实现了给新创建的工作表创建一个新的名字
table.title = 'test'

# 合并C1 D1 
# 法一
# table.merge_cells('C1:D1')
# table.cell(row = 1,column = 3,value = 'pdf/mp3链接')
# 法二
table.merge_cells(start_row=1, start_column=3, end_row=1, end_column=4)
table.cell(1, 3).value = '合并2个单元格'
# 法一不适合批量添加
for i in range(2,10):
    table.merge_cells(start_row=i, start_column=3, end_row=i, end_column=4)

 

Results are as follows:
