Python，openpyxl在设置格式后再加粗首行为什么就报错了呢？

import openpyxl
from openpyxl.styles import Font, Alignment
 
book = openpyxl.load_workbook('测试.xlsx')
ws = book.active
ws.column_dimensions['B'].width = 25
ws.column_dimensions['C'].width = 15
ws.column_dimensions['E'].width = 40
for i in range(1, ws.max_row + 1):
  ws.row_dimensions[i].height = 12.75
for col in ws.columns:
  for cell in col:
  font = Font(name='Arial', size=10)
  cell.font = font
  cell.alignment = Alignment(vertical='center')
# 下面设置首行加粗就报错了（A1:F1），上面都能正常运行，不带下面for循环能正常保存表格
for cell in range(6):
  font = Font(name='Arial', size=10, bold=False)
  cell.font = font
book.save('测试-输出.xlsx')
 
报错内容：
'int' object has no attribute 'font'

你的for cell in range(6) cell不是单元格对象，是数字，当然报错

改成这样

 
import openpyxl
from openpyxl.styles import Font, Alignment
book = openpyxl.load_workbook('测试.xlsx')
ws = book.active
ws.column_dimensions['B'].width = 25
ws.column_dimensions['C'].width = 15
ws.column_dimensions['E'].width = 40
for i in range(1, ws.max_row + 1):
    ws.row_dimensions[i].height = 12.75
for col in ws.columns:
  for cell in col:
    font = Font(name='Arial', size=10)
    cell.font = font
    cell.alignment = Alignment(vertical='center')
# 下面设置首行加粗就报错了（A1:F1），上面都能正常运行，不带下面for循环能正常保存表格
count=0
for i in ws.columns:
    count+=1
    if count>6:
        break
    cell=i[0]
    font = Font(name='Arial', size=40, bold=False)
    cell.font = font
book.save('测试-输出.xlsx')
