openpyxl 合并单元格

在使用openpyxl库中的merge_cells方法可以实现合并单元格的功能。例如，可以使用以下代码合并单元格：

from openpyxl import Workbook
wb = Workbook()
ws = wb.active
ws.merge_cells('A2:D2') # 或者使用ws.merge_cells(start_row=3, start_column=1, end_row=3, end_column=4)
wb.save("merge.xlsx")

这段代码将合并A2到D2单元格的内容。同样，使用unmerge_cells方法可以取消单元格的合并。例如：

from openpyxl import load_workbook
wb = load_workbook("merge.xlsx")
ws = wb.active
ws.unmerge_cells('A2:D2') # 或者使用ws.unmerge_cells(start_row=3, start_column=1, end_row=3, end_column=4)
wb.save("merge.xlsx")

这段代码将取消A2到D2单元格的合并。通过使用range_string参数，还可以合并或取消合并多个单元格。例如：

from openpyxl import Workbook
wb = Workbook()
ws = wb.active
ws.merge_cells(range_string='A1:B3')
ws.unmerge_cells(range_string='A1:B3')
wb.save("merge.xlsx")

这段代码将合并A1到B3单元格，并取消合并。希望这些代码可以帮助到你。
