Using this extension, you can set CDK data-table datasource with an instance of TableDataSource.

Using TableDataSource allows you to have some row related methods and data to implement add/edit/remove elements:
``typescript
class TableElement {
id: number;
editing: boolean;
currentData?: T;
originalData: T;
source: TableDataSource;
validator: FormGroup; // Used only in reactive forms.

delete(): void;
confirmEditCreate(): boolean;
startEdit(): void;
cancelOrDelete(): void;
isValid(): boolean; // Used only in reactive forms.
}
`

`typescript
class TableDataSource {

constructor(
data: T[],
dataType?: new () => T,
validatorService?: ValidatorService,
config = { prependNewElements: false, suppressErrors: false });

datasourceSubject: Subject;

updateDatasource(data: T[], options = { emitEvent: true }): void;

createNew(): void;

getRow(id: number): TableElement;
}
`
