#### What is the expected behavior?
it should work fine with/without mat-tab

#### What is the current behavior?
Empty rows are created and displaying

#### What are the steps to reproduce?
Providing a StackBlitz reproduction is the *best* way to share your issue.

StackBlitz starter: https://goo.gl/wwnhMV

Step 1: Go to "https://stackblitz.com/edit/angular-material-expandable-table-rows?file=app%2Ftable%2Ftable.component.ts"

Step 2: Add Mat-tab module in app.module.ts "import {MatTabsModule} from '@angular/material/tabs';"

Step 3: Add the following code at the top, in table.componenet.html

"
Content 1
Content 2
Content 3
"

#### Which versions of Angular, Material, OS, TypeScript, browsers are affected?

#### Is there anything else we should know?

Comienza con la reproducción en StackBlitz y compara table.component.html y table.component.ts antes y después de colocar la tabla dentro de mat-tab. Comprueba app.module.ts para verificar MatTabsModule y luego reproduce las filas vacías cambiando de pestaña. La tarea estará terminada cuando la tabla multiTemplateDataRows muestre su contenido correctamente después de salir de la primera pestaña y volver a ella.
