Bigtable stores data in rows, indexes by row keys. Each row may contain multiple column families, each column family might contain multiple columns, and each column has multiple cells indexed by timestamp. Notice that the storage is sparse, column families, columns, and timestamps might contain zero cells.
This function does not participate in overload resolution ifValueTypeis not an integral type. The case for integral types is handled by a separate overload.
Create a cell and fill it with data, but with empty labels.
