for instance, if I have a table with 3 columns, (i.e. col1, col2, col3), can I do something like this: ``` df >> select(X.col1:X.col3) ```

When I set `CORS_ORIGIN_ALLOW_ALL = True`, I can see `Access-Control-Allow-Origin: *` in the response header. However, when I set it to false, and use white list, I cannot see `Access-Control-Allow-Origin`...
