Angular 6 - 对所有表列进行排序仅适用于两列而不是全部

Question

我正在尝试对有棱角的材料进行排序MatTable，MatSort但问题是我只能对我的两列进行排序，MatTable但我想要的是对所有列进行排序，但我不明白为什么它不起作用......我可以单击箭头，就像我想对表的数据进行排序时一样，但除了列multiple和occupation排序良好之外什么也没有发生。

这是我的代码（我很好地导入MatSortModule到我的app.module.ts）：

csr.component.ts

import {AfterViewInit, Component, OnInit, ViewChild} from '@angular/core';
import {PosteCSRPoste, PosteCSRService} from '../../api';
import {MatSort, MatTableDataSource} from '@angular/material';

@Component({
  selector: 'app-csr',
  templateUrl: './csr.component.html',
  styleUrls: [
    './csr.component.css',
    '../app.component.css'
  ]
})
export class CsrComponent implements OnInit, AfterViewInit {
  displayedColumns = [
    'disciplineCsd',
    'disciplineCsr',
    'multiple',
    'communeIdentique',
    'etablissementCsd',
    'etablissementCsr',
    'occupation'
  ];

  postes = new MatTableDataSource<PosteCSRPoste>();

  @ViewChild(MatSort) sort: MatSort;

  constructor(private posteCSRService: PosteCSRService) {
  }

  ngOnInit(): void {
    this.getPostesCSR();
  }

  ngAfterViewInit(): void {
    this.postes.sort = this.sort;

  }

  getPostesCSR(): void {
    this.posteCSRService.getPosteCSRCollection().subscribe(data => {
      this.postes.data = data['hydra:member'];
    });
  }
}

csr.component.html

<table mat-table [dataSource]="postes" matSort class="table table-hover table-bordered mat-elevation-z8">
  <ng-container matColumnDef="disciplineCsd">
    <th mat-header-cell *matHeaderCellDef mat-sort-header scope="col">Discipline CSD</th>
    <td mat-cell *matCellDef="let poste">{{ poste.disciplineCsd.nom | capitalize }}</td>
  </ng-container>

  <ng-container matColumnDef="disciplineCsr">
    <th mat-header-cell *matHeaderCellDef mat-sort-header scope="col">Discipline CSR</th>
    <td mat-cell *matCellDef="let poste">{{ poste.disciplineCsr.nom | capitalize }}</td>
  </ng-container>

  <ng-container matColumnDef="multiple">
    <th mat-header-cell *matHeaderCellDef mat-sort-header scope="col">Multiple</th>
    <td mat-cell *matCellDef="let poste">
      <ng-container *ngIf="poste.multiple; else nonMultiple">
        Multiple
      </ng-container>

      <ng-template #nonMultiple>
        Non multiple
      </ng-template>
    </td>
  </ng-container>

  <ng-container matColumnDef="communeIdentique">
    <th mat-header-cell *matHeaderCellDef mat-sort-header scope="col">Même commune</th>
    <td mat-cell *matCellDef="let poste">
      <ng-container *ngIf="poste.communesIdentiques; else communesDifferentes">
        Mêmes communes
      </ng-container>

      <ng-template #communesDifferentes>
        Communes différentes
      </ng-template>
    </td>
  </ng-container>

  <ng-container matColumnDef="etablissementCsd">
    <th mat-header-cell *matHeaderCellDef mat-sort-header scope="col">Établissement CSD</th>
    <td mat-cell *matCellDef="let poste">{{ poste.etablissementCsd.nom }}</td>
  </ng-container>

  <ng-container matColumnDef="etablissementCsr">
    <th mat-header-cell *matHeaderCellDef mat-sort-header scope="col">Établissement CSR</th>
    <td mat-cell *matCellDef="let poste">{{ poste.etablissementCsr.nom }}</td>
  </ng-container>

  <ng-container matColumnDef="occupation">
    <th mat-header-cell *matHeaderCellDef mat-sort-header scope="col">Occupation</th>
    <td mat-cell *matCellDef="let poste">
      <ng-container *ngIf="poste.occupation; else vacant">
        Occupé
      </ng-container>

      <ng-template #vacant>
        Vacant
      </ng-template>
    </td>
  </ng-container>

  <tr mat-header-row *matHeaderRowDef="displayedColumns"></tr>
  <tr mat-row *matRowDef="let row; columns: displayedColumns;"></tr>
</table>

请告诉我我做错了什么。

这个答案解决了我的问题。

该matColumnDef属性必须与您的模型同名
