https://material.angular.io/components/table/overview ),但当我将cdk前缀更改为md时,会出现以下错误。。。

未捕获错误:模板分析错误:无法绑定到“mdHeaderRowDef” 1.如果“md header row”是一个角度分量,并且具有“mdHeaderRowDef”输入,则验证它是否是此模块的一部分。 2.如果“md header row”是Web组件,则将“CUSTOM\u ELEMENTS\u SCHEMA”添加到“@NgModule”。此组件的架构以抑制此消息。 3.要允许任何属性,请将“NO\u ERRORS\u SCHEMA”添加到“@NgModule”。此组件的架构。

import {Component, OnInit, ViewChild} from '@angular/core';
import {DataSource} from '@angular/cdk';
import { CdkTableModule } from '@angular/cdk';
import { Observable } from 'rxjs/Observable';
import 'rxjs/add/observable/of';
import 'rxjs/add/operator/first';
import 'rxjs/add/operator/startWith';
import 'rxjs/add/operator/catch';
import 'rxjs/add/operator/switchMap';
import 'rxjs/add/observable/merge';
import 'rxjs/add/observable/of';
import 'rxjs/add/observable/interval';
import 'rxjs/add/operator/map';

我正在导入CdkTableModule,当我使用cdk前缀时,表会按预期显示。。。

<md-table [dataSource]="dataSource">

  <ng-container cdkColumnDef="number">
    <md-header-cell *cdkHeaderCellDef> number </md-header-cell>
    <md-cell *cdkCellDef="let element"><a routerLink="{{element.number}}"> {{element.number}} </a></md-cell>
  </ng-container>

  <ng-container cdkColumnDef="book">
    <md-header-cell *cdkHeaderCellDef> book </md-header-cell>
    <md-cell *cdkCellDef="let element"> {{element.book}} </md-cell>
  </ng-container>

  <md-header-row *cdkHeaderRowDef="['number', 'book']"></md-header-row>
  <md-row *cdkRowDef="let row; columns: ['number', 'book']"></md-row>
</md-table>

... 但如果我把“cdk”改成“md”

<md-table [dataSource]="dataSource">

  <ng-container mdColumnDef="number">
    <md-header-cell *mdHeaderCellDef> number </md-header-cell>
    <md-cell *mdCellDef="let element"><a routerLink="{{element.number}}"> {{element.number}} </a></md-cell>
  </ng-container>

  <ng-container mdColumnDef="book">
    <md-header-cell *mdHeaderCellDef> book </md-header-cell>
    <md-cell *mdCellDef="let element"> {{element.book}} </md-cell>
  </ng-container>

  <md-header-row *mdHeaderRowDef="['number', 'book']"></md-header-row>
  <md-row *mdRowDef="let row; columns: ['number', 'book']"></md-row>
</md-table>

P、这是我的主要应用程序。单元ts import语句,以防有帮助

imports: [
BrowserModule,
FormsModule,
HttpModule,
AppRoutingModule,
ReactiveFormsModule,
BrowserAnimationsModule,
MdAutocompleteModule,
MdButtonModule,
MdButtonToggleModule,
MdCardModule,

npm更新--保存

并将@angular/cdk和@angular/material更新为2.0.0-beta。10

包装内。json

 "@angular/material": "^2.0.0-beta.10",
 "@angular/cdk": "^2.0.0-beta.10",

这破坏了一些东西,所以我不得不四处挖掘,需要更新数据源和CdkTableModule的导入

       import { CdkTableModule} from '@angular/cdk/table';
       import {DataSource} from '@angular/cdk/table';

组成部分html

 <md-table [dataSource]="dataSource">

    <ng-container mdColumnDef="number">
      <md-header-cell *mdHeaderCellDef> number </md-header-cell>
      <md-cell *mdCellDef="let element"><a routerLink="{{element.number}}"> {{element.number}} </a></md-cell>
    </ng-container>

    <ng-container mdColumnDef="book">
      <md-header-cell *mdHeaderCellDef> book </md-header-cell>
      <md-cell *mdCellDef="let element"> {{element.book}} </md-cell>
    </ng-container>

    <ng-container mdColumnDef="s1">
      <md-header-cell *mdHeaderCellDef> S1 </md-header-cell>
      <md-cell *mdCellDef="let element"> {{element.sections[0] ? element.sections[0].type : ''}} {{element.sections[0] && element.sections[0].qs ? '('+element.sections[0].qs.length+')' : ''}}</md-cell>
    </ng-container>

    <ng-container mdColumnDef="s2">
      <md-header-cell *mdHeaderCellDef> S2 </md-header-cell>
      <md-cell *mdCellDef="let element"> {{element.sections[1] ? element.sections[1].type : ''}} {{element.sections[1] && element.sections[1].qs  ? '('+element.sections[1].qs.length+')' : ''}} </md-cell>
    </ng-container>

    <ng-container mdColumnDef="s3">
      <md-header-cell *mdHeaderCellDef> S3 </md-header-cell>
      <md-cell *mdCellDef="let element"> {{element.sections[2] ? element.sections[2].type : ''}} {{element.sections[2] && element.sections[2].qs ? '('+element.sections[2].qs.length+')' : ''}}</md-cell>
    </ng-container>

    <ng-container mdColumnDef="s4">
      <md-header-cell *mdHeaderCellDef> S4 </md-header-cell>
      <md-cell *mdCellDef="let element"> {{element.sections[3] ? element.sections[3].type : ''}} {{element.sections[3] && element.sections[3].qs ? '('+element.sections[3].qs.length+')' : ''}}</md-cell>
    </ng-container>

    <md-header-row *mdHeaderRowDef="['number', 'book', 's1', 's2', 's3', 's4']"></md-header-row>
    <md-row *mdRowDef="let row; columns: ['number', 'book', 's1', 's2', 's3', 's4']"></md-row>
  </md-table>

 import {Component, OnInit} from '@angular/core';

 // Data Table imports.
     import { DataSource } from '@angular/cdk/table';
     import { Observable } from 'rxjs/Observable';
     import 'rxjs/add/observable/of';

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

   pts: Pt[];
   dataSource = new ExampleDataSource(this.ptService);
   constructor( public ptService: PtService ) { }
   ngOnInit() {
     this.pt = this.ptService.getPts();
   }
 }

 export class ExampleDataSource extends DataSource<any> {
   data = this.ptService.getPts();
   constructor( public ptService: PtService ) { super() }
   /** Connect function called by the table to retrieve one stream containing the data to render. */
   connect(): Observable<Pt[]> {
     return Observable.of(this.data);
   }
   disconnect() {}
 }

唷!

进口 MatTableModule

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

@NgModule({
  imports: [
     MatTableModule
  ]
})
export class AppModule { }

从“^2.0.0-beta.11”开始,所有以 md 无效,应替换为 mat
