How Install:

  1. Install django-tables2-column-shifter using:

        pip install django-tables2-column-shifter
    
    or
    
        pip install git+https://github.com/djk2/django-tables2-column-shifter
    
    or
    
        pip install django-tables2-column-shifter.zip
    
    or
    
        pip install django-tables2-column-shifter.tar.gz
  2. Add django_tables2_column_shifter to your INSTALLED_APPS setting (after django_tables2) like this

    INSTALLED_APPS = [
        ...,
        'django_tables2',
        'django_tables2_column_shifter',
        ...,
    ]
  3. Add path to js script: django_tables2_column_shifter.min.js in your base django template. Script must be add after jquery.js and before </body> tag.

base.html:

{% load static %}

<body>
    ...
    ...
    <script src="{% static "jquery.min.js" %}"></script> {# require #}
    <script
        type="text/javascript"
        src="{% static "django_tables2_column_shifter/js/django_tables2_column_shifter.min.js" %}">
    </script>
</body>

Usage:

To use app, you must inherit your table class from django_tables2_column_shifter.tables.ColumnShiftTable

models.py - create normal model:

from django.db import models

class MyModel(models.Model):
    first_name = models.CharField("First name", max_length=50)
    last_name = models.CharField("Last name", max_length=50)

tables.py - change inherit to ColumnShiftTable:

from django_tables2_column_shifter.tables import ColumnShiftTable
from app.models import MyModel

# By default you probably inherit from django_table2.Table
# Change inherit to ColumnShiftTable
class MyModelTable(ColumnShiftTable):
    class Meta:
        model = MyModel

views.py - In your view, nothing changes:

from .tables import MyModelTable
from .models import MyModel

def simple_list(request):
    queryset = MyModel.objects.all()
    table = MyModelTable(queryset)
    return render(request, 'template.html', {'table': table})

template.html - use default render_table tag to display table object (using bootstrap3 / bootstrap4):

{% extends "base.html" %}
{% load django_tables2 %}
{% render_table table %}

Warnings:

  • Warning : - If you use {% render_table %} tag with queryset (not table class instance), django-tables2-column-shifter will not be work. Queryset does not have template attribute:

    {% load django_tables2 %}
    {% render_table queryset %} {# not work #}
  • Warning : - If you use a different template than django_tables2_column_shifter/table.html to render your table, probably django-tables2-column-shifter will not be work. Your custom template should inherit from django_tables2_column_shifter/bootstrap3.html

Customizing:

  1. If you use more then one instance of the same Table class, you should use a different prefix for each instance:

    tab1 = MyModelTable(queryset, prefix='tab1')
    tab2 = MyModelTable(queryset, prefix='tab2')
    tab3 = MyModelTable(queryset, prefix='tab3')
  2. To disable shifter mechanism - set False to shift_table_column in your table class (default value is True):

    class MyModelTable(ColumnShiftTable):
       shift_table_column = False
       ...
  3. By default, all columns from sequence are visible, if you want limit visible columns, override method get_column_default_show(self) like that:

    class MyModelTable(ColumnShiftTable):
        def get_column_default_show(self):
            self.column_default_show = ['column1', 'column2']
            return super(MyModelTable, self).get_column_default_show()
