如何在Openpyxl中根据单元格的最大值返回头部字符串

from openpyxl import Workbook, load_workbook

workbook = load_workbook('filename.xlsx')

worksheet = workbook.active

max_value = 0
header_string = ''

for row in worksheet.iter_rows():
    for cell in row:
        if isinstance(cell.value, int) or isinstance(cell.value, float):
            if cell.value > max_value:
                max_value = cell.value
                header_string = worksheet.cell(row=1, column=cell.column).value

print("最大值:", max_value)
print("对应的头部字符串:", header_string)

from openpyxl import load_workbook

workbook = load_workbook('filename.xlsx')
worksheet = workbook.active

max_value = 0
header_string = ''

for row in worksheet.iter_rows():
    for cell in row:
        if isinstance(cell.value, int) or isinstance(cell.value, float):
            if cell.value > max_value:
                max_value = cell.value
                header_string = worksheet.cell(row=1, column=cell.column).value

print("最大值:", max_value)
print("对应的头部字符串:", header_string)
