Angular 6 - 对所有表列进行排序仅适用于两列而不是全部列 [英] Angular 6 - Sorting all table columns works on only two columns instead of all

问题描述

我正在尝试使用 MatSort 对角度素材进行 MatTable 的排序，但问题是我只能排序我的 MatTable 的两列，但我想要的是排序我的所有列，我不明白为什么它不起作用...我可以点击箭头像当我想对我的表的数据进行排序但没有任何事情发生，除了列多个和占用哪些排序很好。

I'm trying to sort a MatTable with MatSort of angular material but the problem is I can sort only two columns of my MatTable but what I want is to sorting all my columns and I don't understand why it doesn't work... I can click on the arrow like when I want to sort data of my table but nothing happens except with column multiple and occupation which are sorting well.

这是我的代码（我正在将 MatSortModule 导入我的 app.module。 ts ）：

Here is my code (I'm well importing MatSortModule into my app.module.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

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">

  <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。

Please tell me what I'm doing wrong.

推荐答案

此答案解决了我的问题。

matColumnDef 属性必须与您的模型同名

The matColumnDef property must have the same name as your model
