python使用openpyxl实现批量调整字体和样式

from openpyxl.styles import Font
from openpyxl import load_workbook

'''
Font(name=字体名称,size=字体大小,bold=是否加粗,italic=是否斜体,color=字体颜色)
'''

workbook = load_workbook(filename="../excelDemo/testCase.xlsx")
sheet = workbook.active
cell = sheet["A1"]
font = Font(name="微软雅黑",size=20,bold=True,italic=True,color="FF0000")
# 这个 color 是 RGB 的 16 进制表示
cell.font = font
workbook.save(filename="../excelDemo/testCase.xlsx")

from openpyxl.styles import Font
from openpyxl import load_workbook


workbook = load_workbook(filename="../excelDemo/testCase.xlsx")
sheet = workbook.active

cell = sheet["A1"]
font = cell.font
print(font.name, font.size, font.bold, font.italic, font.color)


'''
输出结果：
微软雅黑 20.0 True True <openpyxl.styles.colors.Color object>
Parameters:
