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

I am new in angular 5 development. I am trying to develop a data table with angular material using the example provided here: "https://material.angular.io/components/table/examples".

I am getting an error saying Can't bind to 'dataSource' since it isn't a known property of 'table'.

Please help.

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
    // ...
  ]
})

Thanx to @Jota.Toledo, I got the solution for my table creation. Please find the working code below:

component.html

<mat-table #table [dataSource]="dataSource" matSort>
  <ng-container matColumnDef="{{column.id}}" *ngFor="let column of columnNames">
    <mat-header-cell *matHeaderCellDef mat-sort-header> {{column.value}}</mat-header-cell>
    <mat-cell *matCellDef="let element"> {{element[column.id]}}</mat-cell>
  </ng-container>

  <mat-header-row *matHeaderRowDef="displayedColumns"></mat-header-row>
  <mat-row *matRowDef="let row; columns: displayedColumns;"></mat-row>
</mat-table>

component.ts

import { Component, OnInit, ViewChild } from '@angular/core';
import { MatTableDataSource, MatSort } from '@angular/material';
import { DataSource } from '@angular/cdk/table';

@Component({
  selector: 'app-m',
  templateUrl: './m.component.html',
  styleUrls: ['./m.component.css'],
})
export class MComponent implements OnInit {

  dataSource;
  displayedColumns = [];
  @ViewChild(MatSort) sort: MatSort;

  /**
   * Pre-defined columns list for user table
   */
  columnNames = [{
    id: 'position',
    value: 'No.',

  }, {
    id: 'name',
    value: 'Name',
  },
    {
      id: 'weight',
      value: 'Weight',
    },
    {
      id: 'symbol',
      value: 'Symbol',
    }];

  ngOnInit() {
    this.displayedColumns = this.columnNames.map(x => x.id);
    this.createTable();
  }

  createTable() {
    let tableArr: Element[] = [{ position: 1, name: 'Hydrogen', weight: 1.0079, symbol: 'H' },
      { position: 2, name: 'Helium', weight: 4.0026, symbol: 'He' },
      { position: 3, name: 'Lithium', weight: 6.941, symbol: 'Li' },
      { position: 4, name: 'Beryllium', weight: 9.0122, symbol: 'Be' },
      { position: 5, name: 'Boron', weight: 10.811, symbol: 'B' },
      { position: 6, name: 'Carbon', weight: 12.0107, symbol: 'C' },
    ];
    this.dataSource = new MatTableDataSource(tableArr);
    this.dataSource.sort = this.sort;
  }
}

export interface Element {
  position: number,
  name: string,
  weight: number,
  symbol: string
}

app.module.ts

imports: [
  MatSortModule,
  MatTableModule,
],

• Angular Core v6.0.2,
• Angular Material, v6.0.2,
• Angular CLI v6.0.0 (globally v6.1.2)

I had this issue when running ng test, so to fix it, I added to my xyz.component.spec.ts file:

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

And added it to imports section in TestBed.configureTestingModule({}):

beforeEach(async(() => {
    TestBed.configureTestingModule({
      imports: [ ReactiveFormsModule, HttpClientModule, RouterTestingModule, MatTableModule ],
      declarations: [ BookComponent ],
      schemas: [ CUSTOM_ELEMENTS_SCHEMA ]
    })
    .compileComponents();
}));

if your "import { MatTableModule } from '@angular/material';" is on a shared module, make sure you export it.

sharedmodule.ts:

import { MatTableModule } from '@angular/material' 

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

then on your custom module where you define the component that use material table:

custommodule.ts:

@NgModule({
imports: [ sharedmodule ]     
})

Material example is using the wrong table tags. Change

<table mat-table></table>
<th mat-header-cell></th>
<td mat-cell></td>

<tr mat-header-row></tr>
<tr mat-row></tr>

to

<mat-table></mat-table>
<mat-header-cell></mat-header-cell>
<mat-cell></mat-cell>

<mat-header-row></<mat-header-row>
<mat-row></<mat-row>
