Kendo UI for Angular2 - Grid How to Add Columns Dynamically

You can use ngFor to make a variable number of columns:

    <kendo-grid [data]="gridData">
      <ng-template ngFor [ngForOf]="columns" let-column>
        <kendo-grid-column field="{{column}}"></kendo-grid-column>
      </ng-template>
    </kendo-grid>

If you want to try this out, see the "showing and hiding columns" demo in the docs (scroll down in the columns examples).
