Angular Material报错:Can't bind to 'dataSource' since it isn't a known property of 'md-table'
官方示例
<div class="example-container mat-elevation-z8">
<mat-table #table [dataSource]="dataSource">
<!--- Note that these columns can be defined in any order.
The actual rendered columns are set as a property on the row definition" -->
<!-- Position Column -->
<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>
</div>
错误信息
Uncaught Error: Template parse errors:
Can't bind to 'dataSource' since it isn't a known property of 'mat-table'.
1. If 'mat-table' is an Angular component and it has 'dataSource' input, then verify that it is part of this module.
2. If 'mat-table' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.
版本信息
Angular:4.2.4
Angular Material:2.00-beta.12
Angular CDK:2.00-beta.12
解决方法
官方的文档里只要求需要导入MatTableModule。
import {MatTableModule} from '@angular/material';
dataSource属于CDK的CdkTableModule模块,也是需要导入CdkTableModule:
import {CdkTableModule} from "@angular/cdk/table";
