I'm trying to create a table using Angular Material Table, in the examples there is always the import:
import {MatTableDataSource} from '@angular/material';
I'm trying to do the same but I'm getting an error: "Module '../node_modules/@angular/material/material' has no exported member MatTableDataSource.
Is there anything I'm missing?
Here's the package.json versions:
"dependencies": { "@angular/animations": "^4.4.6", "@angular/cdk": "^2.0.0-beta.12", "@angular/common": "^4.2.4", "@angular/compiler": "^4.2.4", "@angular/core": "^4.2.4", "@angular/forms": "^4.2.4", "@angular/http": "^4.2.4", "@angular/material": "^2.0.0-beta.12", "@angular/platform-browser": "^4.2.4", "@angular/platform-browser-dynamic": "^4.2.4", "@angular/router": "^4.2.4", "bootstrap": "^3.3.7", "core-js": "^2.4.1", "pdfmake": "^0.1.33", "rxjs": "^5.4.2", "zone.js": "^0.8.14" }, "devDependencies": { "@angular/cli": "1.4.9", "@angular/compiler-cli": "^4.2.4", "@angular/language-service": "^4.2.4", "@types/jasmine": "~2.5.53", "@types/jasminewd2": "~2.0.2", "@types/node": "~6.0.60", "codelyzer": "~3.2.0", "jasmine-core": "~2.6.2", "jasmine-spec-reporter": "~4.1.0", "karma": "~1.7.0", "karma-chrome-launcher": "~2.1.1", "karma-cli": "~1.0.1", "karma-coverage-istanbul-reporter": "^1.2.1", "karma-jasmine": "~1.1.0", "karma-jasmine-html-reporter": "^0.2.2", "protractor": "~5.1.2", "ts-node": "~3.2.0", "tslint": "~5.7.0", "typescript": "~2.3.3" }
I was having the same problem. Turns out, MatTableDataSource is new feature in Angular Material 5.0.0-rc0. I updated angular 4 to angular 5 and updated angular material to 5.0.0-rc0. (ref: https://github.com/angular/material2/releases)
If it helps, here is my package.json file.

I had the same error and I have two solutions to propose
1. Keep the same package.json (with "@angular/material": "^2.0.0-beta.12") and try to implement this
[Solution found thanks to this: https://github.com/angular/material2/issues/6036]
X.component.html:
<mat-table #table [dataSource]="dataSource"> <ng-container matColumnDef="position"> <mat-header-cell *matHeaderCellDef> No. </mat-header-cell> <mat-cell *matCellDef="let element"> {{element.position}} </mat-cell> </ng-container> <!-- Name Column --> <ng-container matColumnDef="name"> <mat-header-cell *matHeaderCellDef> Name </mat-header-cell> <mat-cell *matCellDef="let element"> {{element.name}} </mat-cell> </ng-container> <!-- Weight Column --> <ng-container matColumnDef="weight"> <mat-header-cell *matHeaderCellDef> Weight </mat-header-cell> <mat-cell *matCellDef="let element"> {{element.weight}} </mat-cell> </ng-container> <!-- Color Column --> <ng-container matColumnDef="symbol"> <mat-header-cell *matHeaderCellDef> Symbol </mat-header-cell> <mat-cell *matCellDef="let element"> {{element.symbol}} </mat-cell> </ng-container> <mat-header-row *matHeaderRowDef="displayedColumns"></mat-header-row> <mat-row *matRowDef="let row; columns: displayedColumns;"></mat-row> </mat-table>
X.component.ts:
import { DataSource } from '@angular/cdk/collections'; @Component({... }) export class XComponent implements OnInit { displayedColumns = ['position', 'name', 'weight', 'symbol']; dataSource: eDataSource; ELEMENT_DATA: 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'}, {position: 7, name: 'Nitrogen', weight: 14.0067, symbol: 'N'}, {position: 8, name: 'Oxygen', weight: 15.9994, symbol: 'O'}, {position: 9, name: 'Fluorine', weight: 18.9984, symbol: 'F'}, {position: 10, name: 'Neon', weight: 20.1797, symbol: 'Ne'}, {position: 11, name: 'Sodium', weight: 22.9897, symbol: 'Na'}, {position: 12, name: 'Magnesium', weight: 24.305, symbol: 'Mg'}, {position: 13, name: 'Aluminum', weight: 26.9815, symbol: 'Al'}, {position: 14, name: 'Silicon', weight: 28.0855, symbol: 'Si'}, {position: 15, name: 'Phosphorus', weight: 30.9738, symbol: 'P'}, {position: 16, name: 'Sulfur', weight: 32.065, symbol: 'S'}, {position: 17, name: 'Chlorine', weight: 35.453, symbol: 'Cl'}, {position: 18, name: 'Argon', weight: 39.948, symbol: 'Ar'}, {position: 19, name: 'Potassium', weight: 39.0983, symbol: 'K'}, {position: 20, name: 'Calcium', weight: 40.078, symbol: 'Ca'}, ]; ngOnInit() { this.dataSource = new eDataSource(this.ELEMENT_DATA); } } export interface Element { name: string; position: number; weight: number; symbol: string; } export class eDataSource extends DataSource<any> { constructor(private element: Element[]) { super(); } connect(): Observable<Element[]> { return Observable.of(this.element); } disconnect() {} }
2. Built another application with this package.json:
{ "name": "design2", "version": "0.0.0", "license": "MIT", "scripts": { "ng": "ng", "start": "ng serve", "build": "ng build", "test": "ng test", "lint": "ng lint", "e2e": "ng e2e" }, "private": true, "dependencies": { "@angular/animations": "^5.0.0", "@angular/cdk": "^5.0.0-rc0", "@angular/common": "^5.0.0", "@angular/compiler": "^5.0.0", "@angular/core": "^5.0.0", "@angular/forms": "^5.0.0", "@angular/http": "^5.0.0", "@angular/material": "^5.0.0-rc0", "@angular/platform-browser": "^5.0.0", "@angular/platform-browser-dynamic": "^5.0.0", "@angular/router": "^5.0.0", "core-js": "^2.4.1", "rxjs": "^5.5.2", "zone.js": "^0.8.14" }, "devDependencies": { "@angular/cli": "1.5.3", "@angular/compiler-cli": "^5.0.0", "@angular/language-service": "^5.0.0", "@types/jasmine": "~2.5.53", "@types/jasminewd2": "~2.0.2", "@types/node": "~6.0.60", "codelyzer": "^4.0.1", "jasmine-core": "~2.6.2", "jasmine-spec-reporter": "~4.1.0", "karma": "~1.7.0", "karma-chrome-launcher": "~2.1.1", "karma-cli": "~1.0.1", "karma-coverage-istanbul-reporter": "^1.2.1", "karma-jasmine": "~1.1.0", "karma-jasmine-html-reporter": "^0.2.2", "protractor": "~5.1.2", "ts-node": "~3.2.0", "tslint": "~5.7.0", "typescript": "~2.4.2" } }
And now it is perfectly working with the example from https://material.angular.io/components/table/overview.
My app.module.ts:
import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { MatTableModule } from '@angular/material/table'; import { AppComponent } from './app.component'; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, MatTableModule ], providers: [], bootstrap: [AppComponent] }) export class AppModule { }
My X.component.ts:
import { Component } from '@angular/core'; import { MatTableDataSource } from '@angular/material/table'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { title = 'app'; displayedColumns = ['position', 'name', 'weight', 'symbol']; dataSource = new MatTableDataSource<Element>(ELEMENT_DATA); } export interface Element { name: string; position: number; weight: number; symbol: string; } const ELEMENT_DATA: 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'}, {position: 7, name: 'Nitrogen', weight: 14.0067, symbol: 'N'}, {position: 8, name: 'Oxygen', weight: 15.9994, symbol: 'O'}, {position: 9, name: 'Fluorine', weight: 18.9984, symbol: 'F'}, {position: 10, name: 'Neon', weight: 20.1797, symbol: 'Ne'}, {position: 11, name: 'Sodium', weight: 22.9897, symbol: 'Na'}, {position: 12, name: 'Magnesium', weight: 24.305, symbol: 'Mg'}, {position: 13, name: 'Aluminum', weight: 26.9815, symbol: 'Al'}, {position: 14, name: 'Silicon', weight: 28.0855, symbol: 'Si'}, {position: 15, name: 'Phosphorus', weight: 30.9738, symbol: 'P'}, {position: 16, name: 'Sulfur', weight: 32.065, symbol: 'S'}, {position: 17, name: 'Chlorine', weight: 35.453, symbol: 'Cl'}, {position: 18, name: 'Argon', weight: 39.948, symbol: 'Ar'}, {position: 19, name: 'Potassium', weight: 39.0983, symbol: 'K'}, {position: 20, name: 'Calcium', weight: 40.078, symbol: 'Ca'}, ];
And my X.component.html:
<mat-table #table [dataSource]="dataSource"> <ng-container matColumnDef="position"> <mat-header-cell *matHeaderCellDef> No. </mat-header-cell> <mat-cell *matCellDef="let element"> {{element.position}} </mat-cell> </ng-container> <ng-container matColumnDef="name"> <mat-header-cell *matHeaderCellDef> Name </mat-header-cell> <mat-cell *matCellDef="let element"> {{element.name}} </mat-cell> </ng-container> <ng-container matColumnDef="weight"> <mat-header-cell *matHeaderCellDef> Weight </mat-header-cell> <mat-cell *matCellDef="let element"> {{element.weight}} </mat-cell> </ng-container> <ng-container matColumnDef="symbol"> <mat-header-cell *matHeaderCellDef> Symbol </mat-header-cell> <mat-cell *matCellDef="let element"> {{element.symbol}} </mat-cell> </ng-container> <mat-header-row *matHeaderRowDef="displayedColumns"></mat-header-row> <mat-row *matRowDef="let row; columns: displayedColumns;"></mat-row> </mat-table>
All right :)
