如何显示django column和help_text水平？

Question

我这样写了我的模型：

from django.db import models
from ckeditor.fields import RichTextField
from django import forms
from django.contrib import admin
from ckeditor.widgets import CKEditorWidget
import datetime

class Post(models.Model):
    title = models.CharField(max_length=200,default="no-title")
    tags = models.CharField(max_length=200,default="blog",help_text="comma separated")
    summary = models.TextField(max_length=300,default="summary",help_text="Article short introduction")
    cover = models.ImageField("cover img",upload_to="blog/")
    last_activity = models.DateTimeField(default=datetime.datetime.now,auto_now=True)
    keywords = models.CharField(max_length=200,default="no-keyword",help_text="comma separated")
    content = RichTextField()

    def __unicode__(self):
        return self.title

class PostAdminForm(forms.ModelForm):
    content = forms.CharField(widget=CKEditorWidget())
    fields = ('title','tags')
    class Meta:
        model = Post

class PostAdmin(admin.ModelAdmin):
    form = PostAdminForm

    readonly_fields = ('last_activity',)

admin.site.register(Post, PostAdmin)

我的模型显示在管理页面中，如下所示：

您可以看到Tags列输入文本和垂直显示的help_text字符串，这不是我想要的，我想显示Tags列输入文本和{ {1}}水平属性。
