如何用openpyxl / python读取excel文件的合并单元格值？

import openpyxl

workbook = openpyxl.load_workbook('example.xlsx')

sheet = workbook.active

merged_cells = sheet.merged_cells

for merged_cell in merged_cells:
    start_row, start_col, end_row, end_col = merged_cell.min_row, merged_cell.min_col, merged_cell.max_row, merged_cell.max_col

merged_cell_value = sheet.cell(row=start_row, column=start_col).value

import openpyxl

def read_merged_cell_value(file_path, sheet_name, row, column):
    workbook = openpyxl.load_workbook(file_path)
    sheet = workbook[sheet_name]
    merged_cells = sheet.merged_cells

    for merged_cell in merged_cells:
        start_row, start_col, end_row, end_col = merged_cell.min_row, merged_cell.min_col, merged_cell.max_row, merged_cell.max_col
        if start_row <= row <= end_row and start_col <= column <= end_col:
            return sheet.cell(row=start_row, column=start_col).value

    return None

# 示例用法
file_path = 'example.xlsx'
sheet_name = 'Sheet1'
row = 2
column = 3

merged_cell_value = read_merged_cell_value(file_path, sheet_name, row, column)
print(merged_cell_value)
