_tkinter.TclError: can't find package Tktable
You should install tktable...Go this link: https://pypi.python.org/pypi/tkintertable/1.1.2
Download it...Extract file.And open the folder which has been extracted.Open command prompt in same folder and type this command:
python setup.py install
Wait while it is being set up...After doing it try again.
After searching for a long time I found this

which solves my problem.
Now the TkTableCalender.py is running properly.
