django使用xlwt导出excel文件

这里只是mark一下导出的方法，并没有做什么REST处理和异常处理。

维护统一的style样式，可以使导出的数据更加美观。

def export_excel(request):  
    # 设置HttpResponse的类型
    response = HttpResponse(content_type='application/vnd.ms-excel')  
    response['Content-Disposition'] = 'attachment;filename=user.xls'  
    # new一个文件
    wb = xlwt.Workbook(encoding = 'utf-8')  
    # new一个sheet
    sheet = wb.add_sheet(u'人员表单')
    # 维护一些样式， style_heading, style_body, style_red, style_green
　　 style_heading = xlwt.easyxf("""
        font:
            name Arial,
            colour_index white,
