浅谈openpyxl库,遇到批量合并单元格的问题

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)

 if cr.coord not in self.merged_cells:
  raise ValueError("Cell range {0} is not merged".format(cr.coord))
 
 self.merged_cells.remove(cr) 
 # Deletes the MergedCellRange.
 # del self._merged_cell_range[cr.bounds]
 # autho : watson
 # aim : deal with the bug about umerger
 # describe : Add the following five lines of code to format the attribute.
 min_col, min_row, max_col, max_row = cr.bounds
 for row in range(min_row, max_row + 1):
  for col in range(min_col, max_col + 1):
  if col == min_col and row == min_row:
   continue
  del self._cells[(row, col)]
