@eagle006 make sure that you install django-datatable-view version from git, I guess pip version is not updated

d:\example_project\example_project\example_app\views.py", line 1355, in datatable_class
select_data = columns.CheckBoxSelectColumn()
AttributeError: module 'datatableview.columns' has no attribute 'CheckBoxSelectColumn'
