Alignment issue in changelist

[Julien Phalip]

This is a different issue than #15290 so I preferred to create a new ticket. This one is quite minor though.

Try this example:

from django.db import models

class MyModel(models.Model):
    name = models.CharField(max_length=100, blank=True)
    title = models.CharField(max_length=100, blank=True)
    content = models.CharField(max_length=100, blank=True)

Admin:

from django.contrib import admin

from .models import MyModel

class MyModelAdmin(admin.ModelAdmin):
    list_display = ('name', 'title', 'content')
    actions = None
    list_display_links = ('title',)

admin.site.register(MyModel, MyModelAdmin)

The content of the first column is centered and not left-aligned like all the other columns are. This is dictated by the CSS, presumably because generally the action checkbox is in the first column, and that needs to be centered.

The attached patch fixes this (minor) issue, though there might be other, more general, approaches to this - perhaps by allowing a callable to provide its own classes? For example, in ModelAdmin.action_checkbox:

    def action_checkbox(self, obj):
        """
        A list_display column containing a checkbox widget.
        """
        return helpers.checkbox.render(helpers.ACTION_CHECKBOX_NAME, force_unicode(obj.pk))
    action_checkbox.short_description = mark_safe('<input type="checkbox" id="action-toggle" />')
    action_checkbox.allow_tags = True
    action_checkbox.css_classes = ['action-checkbox']
