extending MatTableDataSource instead DataSource

[lakinduakash]

If it can extend MatTableDataSource then we can use MatPaginator, MatSort, search etc more easily because in MatTable we can setup those features easily.

Hi @lakinduakash,

There is already an issue regarding this.
As I currently don't have much bandwidth, I can't take in short term, but any help regarding it will be appreciated.
