通过xlwt这个库，可以将数据写入Excel中，而且通过xlwt写excel格式可以控制 颜色、模式、编码、背景色
下面基本上是一个练习，熟悉如何操作xlwt库的
下面是代码，所有的内容，和介绍，基本上都卸载了上面，一步一步来，基本上都可以熟悉。
#coding=utf8
import xlwt,datetime
#创建一个Excel表格
wbk = xlwt.Workbook(encoding='utf-8',style_compression=0)
#为创建的Excel表格添加一个工作表
'''
#第一个为一个sheet名字，第二个确定同一个cell单元是否可以重置
否则重写时，会报Exception: Attempt to overwrite cell: sheetname=u'etsy_sheet' rowx=0 colx=0
'''
sheet = wbk.add_sheet("etsy_sheet",cell_overwrite_ok=True)
sheet.write(0,0,"title")
# sheet.write(0,0,"new_title")##重新设置，需要cell_overwrite_ok=True
sheet.write(0,1,"time")
sheet.write(1,0,"aaaa")
font =xlwt.Font()
font.name="Times New Roman"
font.colour_index=12#11为银绿色 12为蓝色
font.height = 0x00C8 # C8 in Hex (in decimal) = 10 points in height.
#加黑
# font.bold = True
#下划线
font.underline = True
#中划线
# font.struck_out=True

# Setting the Width of a Cell

# Adding a Hyperlink to a Cell
#添加链接
sheet.write(4, 0, xlwt.Formula('HYPERLINK("http://www.google.com";"Google")')) # Outputs the text "Google" linking to http://www.google.com
#Merging Columns and Rows
'''
如：wirte_memrge(6,7,0,3,"second",style)
6,7.指要合并的行数，0.3指要合并的列数，’second‘是输入的文本，style是你设置的风格，可以不写
'''
