NestedStackedInline与NestedTabularInline的区别

我用的是 嵌套的 Django项目中的模型。

下面的代码片段是 模型.py :

from django.db import models
from django.db.models.deletion import CASCADE

class Model_(models.Model):
    name = models.CharField(max_length=50, default="This is a model")
    frequently = models.FloatField(default=1.0)

    def __str__(self):
        return self.name

class SubModel(models.Model):
    name = models.CharField(max_length=100)
    address = models.CharField(max_length=8, default='0x')
    model_ = models.ForeignKey(Model_, on_delete=CASCADE)

    def __str__(self):
        return self.name    

class Metadata(models.Model):
    key = models.CharField(max_length=100)
    value = models.CharField(max_length=100)
    sub_model = models.ForeignKey(SubModel, on_delete=CASCADE)

这是我的 管理.py 脚本:

from django.contrib import admin
from nested_inline.admin import NestedTabularInline, NestedStackedInline,\
    NestedModelAdmin
from <djano-application-name>.models import Model_, SubModel, Metadata

class MetadataAdmin(NestedTabularInline):
    model = Metadata
    extra = 1

class SubModelAdmin(NestedStackedInline):
    model = SubModel
    inlines = [MetadataAdmin]
    extra = 1

class Model_Admin(NestedModelAdmin):
    model = Model_
    inlines = [SubModelAdmin]
    list_display = ['name']

admin.site.register(Model_, Model_Admin)

问题:

有什么区别 NestedStackedInline 和 NestedTabularInline 在里面 管理.py 脚本?
