我想创建可被任何组件使用的可重复使用的角度材料数据表,并且只需要传递所需的列标题和其他表数据。以下是我尝试过的:
我正在关注这个例子:stackblitz
在文件夹中创建shared
文件src/app
夹。和数据表组件也是可重用的。
数据表.component.html:
<table mat-table [dataSource]="dataSource" matSort class="mat-elevation-z8">
<ng-container [matColumnDef]="tableData" *ngFor="let tableData of objectKeys(columnHeader)">
<th mat-header-cell *matHeaderCellDef mat-sort-header> {{columnHeader[tableData]}} </th>
<td mat-cell *matCellDef="let element; let i=index;"> {{element[tableData]}}</td>
</ng-container>
<tr mat-header-row *matHeaderRowDef="objectKeys(columnHeader)"></tr>
<tr mat-row *matRowDef="let row; columns: objectKeys(columnHeader);"></tr>
</table>
数据表.component.ts:
import { Component, OnInit, Input, ViewChild } from '@angular/core';
import { MatSort, MatTableDataSource, MatPaginator } from '@angular/material';
@Component({
selector: 'app-data-table',
templateUrl: './data-table.component.html',
styleUrls: ['./data-table.component.scss']
})
export class DataTableComponent implements OnInit {
@Input() tableData;
@Input() columnHeader;
@Input() source;
objectKeys = Object.keys;
dataSource;
@ViewChild(MatSort, { static: false }) sort: MatSort;
@ViewChild(MatPaginator, { static: false }) paginator: MatPaginator;
constructor() { }
ngOnInit() {
console.log(this.tableData);
this.dataSource = new MatTableDataSource(this.tableData);
this.dataSource.sort = this.sort;
}
applyFilter(filterValue: string) {
this.dataSource.filter = filterValue.trim().toLowerCase();
}
}
现在我app-data-table
在我想要的地方使用选择器。我有配置文件组件,我想在其中使用它。
配置文件-setup.component.html:
<app-data-table [tableData]="tableData" [columnHeader]="columnHeader"></app-data-table>
配置文件-setup.component.ts:
import { Component, OnInit, ViewChild, AfterViewInit } from '@angular/core';
import { ProfileSetUp } from 'src/app/_interface/profile-setup.module';
@Component({
selector: 'app-profile-setup',
templateUrl: './profile-setup.component.html',
styleUrls: ['./profile-setup.component.scss']
})
export class ProfileSetupComponent implements OnInit {
constructor() { }
ngOnInit() {
}
columnHeader = {'profileName': 'Profile Name', 'profileDesc': 'Description', 'adminUser': 'Admin User', 'id': ''};
tableData: ProfileSetUp[] = [
{
id: 1,
profileName: "Cameron Villams",
profileDesc: "Face to face contact",
adminUser: "Iwan Rynders",
action: ""
},
{
id: 2,
profileName: "Charl Angle",
profileDesc: "Face to face contact",
adminUser: "Unknown",
action: ""
},
{
id: 3,
profileName: "Johan Abraham",
profileDesc: "Face to face contact",
adminUser: "Unknown",
action: ""
},
{
id: 4,
profileName: "Niekie Gadgilly",
profileDesc: "Face to face contact",
adminUser: "Unknown",
action: ""
},
{
id: 5,
profileName: "Veer S",
profileDesc: "Face to face contact",
adminUser: "Unknown",
action: ""
}
];
}
配置文件-setup.module:
export interface ProfileSetUp {
id: number;
profileName: string;
profileDesc: string;
adminUser: string;
action: string;
}
我怎样才能有条件地显示数据,有些数据表可能有“编辑”、“删除”按钮,有些没有这些按钮。任何帮助将不胜感激。
