Add new rows to the grid when a pasting a number of rows greater than the number of rows below the selected cell

Sometimes you may be pasting more rows than the grid currently has. In this case you need to add additional rows to fit the remaining pasted rows.

To process a Clipboard paste operation we need to calculate whether the pasted content extends beyond the last row, and add new rows to fit them as needed.

See this approach in the samples below:

This example uses the grid callback:
