the row-major 2D array to be spliced.
the column-index at which to start changing the array.
Optional delete_count: numberthe number of columns to remove. if undefined, all columns from start to the end of the array will be removed.
Rest ...insert_items: Array2DColMajor<T>optionally insert column-major based 2D array items the index of start.
a new column-major 2D array containing the deleted columns.
delete 2 columns from arr2d (starting at column-index 1), and insert 5 new columns in its place.
