使用Python合并与拆分Excel单元格的实用方法

pip install Spire.XLS

from spire.xls import *
from spire.xls.common import *

# 创建工作簿对象
workbook = Workbook()
# 加载现有 Excel 文件
workbook.LoadFromFile("input.xlsx")

# 获取第一个工作表
sheet = workbook.Worksheets[0]

# 合并指定范围的单元格
sheet.Range["A1:D1"].Merge()

# 保存文件
workbook.SaveToFile("merged_cells.xlsx", ExcelVersion.Version2013)
workbook.Dispose()

from spire.xls import *
from spire.xls.common import *

workbook = Workbook()
workbook.LoadFromFile("input.xlsx")

# 合并第 7 列的所有单元格
workbook.Worksheets[0].Columns[6].Merge()

workbook.SaveToFile("merged_column.xlsx", ExcelVersion.Version2013)
workbook.Dispose()

from spire.xls import *
from spire.xls.common import *

workbook = Workbook()
workbook.LoadFromFile("merged_file.xlsx")

# 获取工作表
sheet = workbook.Worksheets[0]

# 拆分指定单元格（该单元格必须是已合并区域的一部分）
sheet.Range["A1"].UnMerge()

workbook.SaveToFile("unmerged_cells.xlsx", ExcelVersion.Version2013)
workbook.Dispose()

# 遍历所有合并区域并拆分
