I've moved this discussion to a new topic as it is not related to the original problem of reading data from a grid or table.
So, based upon your other reply, you are looking to read data from an excel spreadsheet, not as part of a data driven test, but to be able to retrieve data from a specific row and a specific column, is that correct?
If so, start with this topic:

There is Python sample code there that you should be able to use as a starting point for building your functionality. Give this a try and, if you have questions, feel free to ask.
