动态将按钮添加到垫台角材料

问题描述

如何动态添加带有编辑和删除按钮的操作列。我有以下设置

父组件中的数据源

columns: MatTable[] = [
    { columnDef: 'position',header: 'No.',cell: (element: any) => `${element.position}` },{ columnDef: 'name',header: 'Name',cell: (element: any) => `${element.name}` },{ columnDef: 'weight',header: 'Weight',cell: (element: any) => `${element.weight}` },{ columnDef: 'symbol',header: 'Symbol',cell: (element: any) => `${element.symbol}` },{ columnDef: 'action',header: 'action',cell: (element: any) => `${element.action}` }
  ];

const ELEMENT_DATA: PeriodicElement[] = [
  { position: 1,name: 'Hydrogen',weight: 1.0079,symbol: 'H',action:`<a mat-raised-button href="https://www.google.com/" target="_blank">Link</a>` },{ position: 2,name: 'Helium',weight: 4.0026,symbol: 'He',action:`<a (click)="openDialog('Update',element)">Edit</a> | <a (click)="openDialog('Delete',element)">Delete</a>` },{ position: 3,name: 'Lithium',weight: 6.941,symbol: 'Li',{ position: 4,name: 'Beryllium',weight: 9.0122,symbol: 'Be',{ position: 5,name: 'Boron',weight: 10.811,symbol: 'B',{ position: 6,name: 'Carbon',weight: 12.0107,symbol: 'C',{ position: 7,name: 'Nitrogen',weight: 14.0067,symbol: 'N',{ position: 8,name: 'Oxygen',weight: 15.9994,symbol: 'O',{ position: 9,name: 'Fluorine',weight: 18.9984,symbol: 'F',{ position: 10,name: 'Neon',weight: 20.1797,symbol: 'Ne',];

 dataSource = ELEMENT_DATA;

 ngOnInit(): void {
    this.matTableConfig.columns = this.columns;
    this.matTableConfig.filter = false;
    this.matTableConfig.dataSource = this.dataSource;
  }

在子组件中

 @Input() matTableConfig: MatTableConfig;

 <table mat-table [dataSource]="matTableConfig?.dataSource" matSort>
            <ng-container *ngFor="let column of matTableConfig?.columns" matColumnDef={{column.columnDef}}>
                <th mat-header-cell *matHeaderCellDef mat-sort-header> {{ column.header }} </th>
                <td mat-cell *matCellDef="let element"> {{ column.cell(element) }} </td>
            </ng-container>
    
            <tr mat-header-row *matHeaderRowDef="displayedColumns"></tr>
            <tr mat-row *matRowDef="let row; columns: displayedColumns;"></tr>
    
            <!-- Row shown when there is no matching data. -->
            <tr class="mat-row" *matNoDataRow>
                <td class="mat-cell" colspan="columns.length">No data matching the filter</td>
            </tr>
        </table>

解决方法

正如您在评论中向我解释的那样，我提供了一个让人眼花stack乱的示例。

请参阅there

,

例如

<ng-container matColumnDef="delete">
 <th mat-header-cell *matHeaderCellDef style="text-align: right;">{{tr[82].a}}</th>
 <td mat-cell *matCellDef="let element" style="text-align: right;">
 <button mat-icon-button (click)="delProd(element)" [matTooltip]="tr[82].a + ' ' + element.id">
 <mat-icon style="color: crimson">delete</mat-icon>
 </button>
 </td>
</ng-container>
