Can’t bind to ‘dataSource’ since it isn’t a known property of ‘table’

Remember to add MatTableModule in your app.module's imports i.e.

In Angular 9+

import { MatTableModule } from '@angular/material/table'  

@NgModule({
  imports: [
    // ...
    MatTableModule
    // ...
  ]
})

Less than Angular 9

import { MatTableModule } from '@angular/material'  

@NgModule({
  imports: [
    // ...
    MatTableModule
    // ...
  ]
})
