无法找到角度材质MatTableDataSource

2 回答

• 6

  我遇到了同样的问题 . 事实证明，MatTableDataSource是Angular Material 5.0.0-rc0中的新功能 . 我将角度4更新为角度5并将角度材料更新为5.0.0-rc0 . （参考：https://github.com/angular/material2/releases）

  如果有帮助，这是我的package.json文件 .

  我有同样的错误，我有两个建议的解决方案

  1.保持相同的package.json（使用“@ angular / material”：“^ 2.0.0-beta.12”）并尝试实现此功能

  [感谢此解决方案：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.用这个package.json构建了另一个应用程序：

  {
    "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"
    }
  }
  

  现在它完全适用于https://material.angular.io/components/table/overview的例子 .

  我的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 { }
  

  我的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'},
  ];
  

  还有我的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>
  

  行 ：）
