Question on passing data into an editable grid

Hello,
I am currently working with passing data into an editable grid. All the data is currently being passed into the grid in the first row as the entire array instead of each component of the array in a separate row. I have attached both my current code for an editable grid and the rowlayout. Thank you and any help would be greatly appreciated!
