Python uses a GUI library called Tkinter as default. This set of classes allows interactive spreadsheet-style tables to be added into an application. Tkinter is the standard GUI toolkit for python. It is old but still quite popular. There are various libraries that extend Tkinter functionality, such as Pmw, but there is currently no extendable table class for Tkinter. A sample application using these classes is included in the distribution.
This library is also now Python 3 compatible
pip install tkintertable or easy_install tkintertable
You can clone the current source using
git clone https://github.com/dmnfarrell/tkintertable.git
See the wiki for how to use the table in Python.
