feat(cdk/table): Make CdkTableDataSourceInput an exported type

[nuwang91]

Feature Description

Problem

Currently the CdkTableDataSourceInput<T> is not an exported type in cdk/table/table.ts. Therefore consumers of the cdk table might have to duplicate the type definition in their code base when building their components based on cdk table.

Proposed Solution

export the type so that consumer of the cdk table could make use of this type when basing/wrapping their components based on cdk table. #

components/src/cdk/table/table.ts

Line 108 in 73008a4

type CdkTableDataSourceInput<T> = readonly T[] | DataSource<T> | Observable<readonly T[]>;

This behavior is similar to that of TrackByFunction<T>

Example Wrapper

// Unnecessary code duplication
type CdkTableDataSourceInput<T> =
  | readonly T[]
  | DataSource<T>
  | Observable<readonly T[]>;

@Component({
  selector: 'wrapper-table',
  ...
})
export class WrapperTableComponent<T> {
  @Input()
  dataSource: CdkTableDataSourceInput<T>;

  @Input()
  trackBy: TrackByFunction<T>;

  ...
