How do you display a list of lists in a grid with each list being it's one c

@brandonc I would like to prefer to handle the list of lists by creating a rule that handles the list and returns a single value finally which thereby prevents the grid from erring because of the incorrect totalCount which could be either caused by flattening or arrays nested inside arrays. Finally this rule will be invoked in the grid iteratively over the a!gridTextColumn. The other way of doing it is, formatting the data before hand and assigning the formatted data to an array of label value pair structure (as shown in many recipes) or a custom data type built for this purpose. It would be worth by giving the data structure you possess as an example or a structure similar to it, so that the practitioners here could give a good solution.
