More extensive documentation request and some user questions.

This seems an amazing library, but nowhere is clearly explained exactly how you are supposed to update the data in the table, how to access the underlying data structures, and much more. As an example, I'm trying to display the table inside an ipywidget box, and I don't know if it's possible and which function should I use. A practical example of how to construct DataModel class would be very useful too.
Lastly I am using get_state() and setData() to get the data from the table w and to change em, is there any easier way to get the data from the table if using pandas DataFrames like for example a w.to_dataframe() method?

EDIT: I see that using w.datamodel._data i can access the underlying dataframe, but if I change it the table widget doesn't update,is there a way to the refresh the view programmatically?

Review the DataModel entry point and the mentioned get_state(), setData(), datamodel._data, and pandas DataFrame usage. Document how to update and access table data, construct a DataModel, display the table in an ipywidget box, and refresh the view after changing underlying data. Done means these workflows and their supported behavior are clearly explained with practical examples.
