MatSort未定义-Angular 5 [英] MatSort is undefined - Angular 5

问题描述

我正在尝试在我的角度应用程序中实现Material表.分页和筛选器工作正常，但我无法对我的表进行排序.我对MatSort的引用是不确定的.

I'm trying to implement a Material table in my angular application. Pagination and Filter are working fine, but i'm not able to sort my table. My reference to MatSort is undefined.

我确实将其导入AppModule:

I did import it in AppModule:

import {MatTableModule} from '@angular/material/table';
import {MatTooltipModule} from '@angular/material/tooltip';
import {MatButtonModule, MatCheckboxModule,MatPaginatorModule,MatInputModule} from '@angular/material';
import {MatSortModule} from '@angular/material/sort';

...
@NgModule({
  declarations: [...],
  imports: [   
     MatSortModule,
     MatTableModule,
     MatPaginatorModule,
     MatInputModule,
     ...
   ]
  })

这是我的component.ts:

Here is my component.ts:

import { Component, OnInit , ViewChild, AfterViewInit} from '@angular/core';
...
import {MatTableDataSource,MatSort,MatPaginator} from '@angular/material';
...
export class MyClass inplements OnInit, AfterViewInit{
  @ViewChild(MatSort) sort:MatSort;
  @ViewChild(MatPaginator) paginator:MatPaginator;
  ...
  ngAfterViewInit(){
     this.dataSource = new MatTableDataSource(this.fake_data);
     this.dataSource.paginator = this.paginator
     this.dataSource.sort = this.sort
  }
 ...
}

这是我的HTML组件:

And here is my component HTML:

<mat-form-field *ngIf="ready" class="width-80">
   <input matInput (keyup)="applyFilter($event.target.value)" placeholder="Filter">
</mat-form-field>
<mat-table #table class = "mat-elevation-z8 animate" matSort [dataSource]="dataSource" display:flex>
   <ng-container matColumnDef="fake_name">
       <mat-header-cell *matHeaderCellDef mat-sort-header class="columnTitle"><b>{{fake_label.name}}</b></mat-header-cell>
       <mat-cell *matCellDef="let fake;" class="cellContent">{{fake.name}}</mat-cell>
   </ng-container>
   <mat-header-row *matHeaderRowDef="fakeColumns"></mat-header-row>
   <mat-row *matRowDef="let row; columns: fakeColumns" class="animate"></mat-row>
</mat-table>
<mat-paginator [length]="length" [pageSize]="5" [pageSizeOptions]="[5,10,15,20,25,50,100]" showFirstLastButtons></mat-paginator>

有人知道我在做什么吗?

Does anyone know what I'm doing wrong?

推荐答案

可以修复在apps.module.ts中添加的问题:

Issue can be fixed adding in apps.module.ts:

import { MatPaginatorModule,MatSortModule } from '@angular/material';

和:

imports: [
    ....
    MatPaginatorModule,        
    MatSortModule

希望这会有所帮助.
