rowKey function for table rows

[dottorblaster]

Description

We need to have a function inside the table component to determine the key for a row in a flexible way

How was this tested?

Jest tests

Thank you!
Most probably we want to use this function now in all of our tables.
Right?
To avoid the bad practice of the index usage.
By now, I'll at least use it in the place where it creates undesared behaviours.
