Similar to matSort, this would involve creating a directive that captures selection state CdkSelection, directives for per-item toggles e.g. CdkSelectionToggle, as well as integrations specifically for CdkTable. For example, the cdk-table has cdk-text-column as a simple way to add text-only content to a table:

<table mat-table [dataSource]="dataSource">
  <mat-text-column name="employeeId"></mat-text-column>
  ...
</table>

We can do something similar for selection.
