You are directly importing a package which is on the Python path so the
system finds it ok. But, that package (django_tables2) apparently
expects to be imported by some other bit of code which already knows
where your settings.py file lives.

If you want to import it directly it needs to know where to look.

You might need a PYTHONPATH environment variable which specifies the
path to your Django project. If settings.py lives in
C:\webwork\djngony\project\xyz\settings.py. Then your PYTHONPATH needs
to include C:\webwork\djngony

The traceback indicates, you need a DJANGO_SETTINGS_MODULE environment
variable. In my example above it would simply be project.xyz
