利用python中的xlsxwriter库，注意该库只能创建excel.而不支持读取和修改，也不支持XLS格式。

from django.contrib import admin
from django.urls import path, include
from web import views
urlpatterns = [
path('download/',views.download),
path('login/',views.login)
]
2.views.py
def download(request):
document_root = settings.BASE_DIR
dest_filename = os.path.join(document_root,'files','xiao.xlsx')
#dest_filename = document_root + 'files' + file_name
wb = xlsxwriter.Workbook(dest_filename)
print(wb)
ws = wb.add_worksheet("xiashou")
row_num = 0
columns = ["序号",'姓名','年龄','密码']
for colu_num in range(len(columns)):
ws.write(row_num,colu_num,columns[colu_num])

response = FileResponse(excel)
response["Content-Type"] = 'application/octet-stream'
response['Content-Disposition'] = 'attachment;filename="{0}"'.format('xiaoshou.xlsx')
return response
def login(request):
return render(request, 'login.html')
