python之如何使用openpyxl设置单元格样式

import pandas as pd
import datetime
df = pd.read_excel('测试.xlsx')
grouped = df.groupby(['部门'])
current_time = datetime.datetime.now()
current_time = current_time.strftime('%m%d')
print(current_time)
name_list = []
for dtype,group in grouped:
    if "/" in dtype:
        dtype = dtype.replace("/","-")
    group.to_excel(f"./demand/{dtype}{current_time}.xlsx",index = False)
    name_list.append(f"./demand/{dtype}{current_time}.xlsx")

def format_xlsx(file_path):
    import os
    from openpyxl import load_workbook
    from openpyxl.utils import get_column_letter
    from openpyxl.styles import PatternFill, Alignment, Side, Border
    from openpyxl.styles import Font, Color, colors, Border, Side, Alignment
    wb = load_workbook(file_path)
    # 打开工作表
    ws = wb.active
    #设置单元格边框的线条样式
    border_set = Border(left=Side(style='thin', color=colors.BLACK),  # 左边框
                    right=Side(style='thin', color=colors.BLACK),  # 右边框
                    top=Side(style='thin', color=colors.BLACK),  # 上边框
                    bottom=Side(style='thin', color=colors.BLACK))  # 下边框
    #设置单元格内容对齐方式
    for i in ws:
        for j in i:
#             print(j,type(j))
            j.alignment = Alignment(horizontal='center', vertical='center',wrapText = True)
    		j.border = border_set
    #设置单元格宽高
    width = 50
    height = 80
#     height = width * (2.2862 / 0.3612)
    for i in range(2, ws.max_row+1):
        ws.row_dimensions[i].height = height
    for i in range(1, ws.max_column+1):
        ws.column_dimensions[get_column_letter(i)].width = width
    wb.save(file_path)
