如何删除包含pandas的合并excel单元格以进行进一步处理？

import pandas as pd
from openpyxl import load_workbook

df = pd.read_excel('your_file.xlsx')

book = load_workbook('your_file.xlsx')
writer = pd.ExcelWriter('your_output_file.xlsx', engine='openpyxl')
writer.book = book
writer.sheets = dict((ws.title, ws) for ws in book.worksheets)

merged_cells = []
for sheetname in writer.sheets:
    ws = writer.sheets[sheetname]
    for merged_cell in ws.merged_cells.ranges:
        merged_cells.append({
            'sheet': sheetname,
            'start_row': merged_cell.min_row,
            'start_col': merged_cell.min_col,
            'end_row': merged_cell.max_row,
            'end_col': merged_cell.max_col
        })

for cell_range in merged_cells:
    sheet = cell_range['sheet']
    start_row = cell_range['start_row']
    start_col = cell_range['start_col']
    end_row = cell_range['end_row']
    end_col = cell_range['end_col']
    
    for row in range(start_row, end_row + 1):
        for col in range(start_col, end_col + 1):
            cell_value = writer.sheets[sheet].cell(row=row, column=col).value
            writer.sheets[sheet].cell(row=row, column=col).value = cell_value

writer.save()
