一、基础
- 安装openpyxl 模块
pip install openpyxl 或者通过轮子安装
-
font(字体类):字号、字体颜色、下划线等
-
fill(填充类):颜色等
-
border(边框类):设置单元格边框
-
alignment(位置类):对齐方式
-
number_format(格式类):数据格式
-
protection(保护类):写保护
1.1 创建excel文件
from openpyxl import Workbook
wb = Workbook() #创建文件对象
wb.remove(wb["sheet"])
wb.remove(self.wb["sheet"]) #移除掉第一个sheet
ws = wb.create_sheet("{0}蒸汽压力记录表".format(self.sample_name), 0)
#生成所含列总数的大写字母
upper_string_list = string.ascii_uppercase[:self.all_col]
wb.save("e:\sample.xlsx")
1.2 操作单元格
from openpyxl import Workbook
wb = Workbook()
ws1 = wb.create_sheet("Mysheet") #创建一个sheet
ws1["A1"]=123.11
ws1["B2"]="你好"
d = ws1.cell(row=4, column=2, value=10)
print ws1["A1"].value
print ws1["B2"].value
print d.value
# Save the file
wb.save("e:\sample.xlsx")
1.3 对多个单元格
