the row-major 2D array to be spliced.
the row-index at which to start changing the array.
Optionaldelete_count: numberthe number of rows to remove. if undefined, all rows from start to the end of the array will be removed.
optionally insert row-major based 2D array items the index of start.
a new row-major 2D array containing the deleted rows.
delete 1 row from arr2d (starting at row-index 1), and insert 2 new rows in its place.
