原文地址:Python通过Pattern设置单元格底纹及背景色作者:teng
Python通过Pattern设置excel文件的单元格底纹及背景颜色时,无法得到想要设置的单元格颜色所代表的数值,最开始采用笨办法,从0开始不停地测试对应的颜色,最后同事提示不如利用Python写个小程序,将0-256对应的颜色显示出来,从而可以根据自己想要的颜色找到对应的数值。在这里将这段小程序和大家共享一下,就不需要一个个去尝试了。
如果对一个单元格重复操作,会引发
returns error:
# Exception: Attempt to overwrite
cell:
# sheetname=u'sheet 1' rowx=0
colx=0
所以在打开时加cell_overwrite_ok=True
解决
以下为源代码:
# -*-
coding: utf-8 -*-
import xlwt
#新建一个excel文件
file=xlwt.Workbook()
#新建一个sheet
table=file.add_sheet('sheet
name',cell_overwrite_ok=True)
for i in range(0,256):
     stylei= xlwt.XFStyle()
       #初始化样式
     patterni= xlwt.Pattern()
      #为样式创建图案
     patterni.pattern=1         #设置底纹的图案索引,1为实心,2为50%灰色,对                       应为excel文件单元格格式中填充中的图案样式
     patterni.pattern_fore_colour=i  #设置底纹的前景色,对应为excel文件单元格格式                       中填充中的背景色
     patterni.pattern_back_colour=35 #设置底纹的背景色,对应为excel文件单元格格式
                      中填充中的图案颜色
     stylei.pattern=patterni     #为样式设置图案
     table.write(i,0,i,stylei)    #使用样式
file.save('D:/Python27/colour.xls')
Copy after login
