ngFor using ngClass on rows and columns issue

Your first code example is working fine Plunker example

@Component({
  selector: 'my-app',
  styles: [`
    .even { color: red; }
    .odd { color: green; }
    `],
  template: `
  <h2>Hello {{name}}</h2>
  <div *ngFor="let meeting of meetingList; let index=index; let odd=odd; let even=even;"
      class="row"
      [ngClass]="{ odd: odd, even: even }">{{meeting}}
    <div class="col"></div>
    <div class="col"></div>
  </div>
`
})
export class App {
  meetingList = ['a', 'b', 'c'];
}

let index=index;

then [index] = index;

then [class.odd] = "index%2";
