Answer 1

You need to push data in datasource

this.dataSource.data.push({id: 1, name: 'test'})

There is stackblitz example

Answer 2

You need to push data as mentioned by Armen. You also need to call renderRows() method of the table as per suggestion https://material.angular.io/components/table/overview#1-write-your-mat-table-and-provide-data

Please check your updated stackblitz example

Same method can be implemented to delete the row. Just make sure the renderRows method calls everytime the table updates.
