Its something that comes from a grid.
So it has an x columns and y rows with fieldvalue in them.
It can be something like this:

CC 9 10 12 14 16 18 20...
DD 21 31 41 51 61 71 81...
....
It think its called "pivot" or something a like in access.
But Im not sure....
Point is - There can be many rows and many columns.
I would like to fetch all rows as shown above.
Only I dont know the exact amount of ros or columns.
At least 1 of each ....
