你好，当我试图添加材料数据表时，我发现此错误：未捕获错误：模板解析错误：无法绑定到'dataSource'，因为它不是'table'的已知属性 .
- my material version : "@angular/material": "^6.2.1"
- my angular version : "@angular/core": "^6.0.5",
这是我的module.ts
import {BrowserAnimationsModule} from '@angular/platform-browser/animations';
import {MatButtonModule, MatCheckboxModule} from '@angular/material';
import { MatTableModule , MatSortModule } from "@angular/material";
这是我的component.ts文件
import {Component, OnInit, ViewChild} from '@angular/core';
import {MatSort, MatTableDataSource} from '@angular/material';
@Component({
selector: 'app-government-index',
templateUrl: './government-index.component.html',
styleUrls: ['./government-index.component.scss']
})
export class GovernmentIndexComponent implements OnInit {
displayedColumns = ['position', 'name', 'weight', 'symbol'];
dataSource = new MatTableDataSource(ELEMENT_DATA);
@ViewChild(MatSort) sort: MatSort;
ngOnInit() {
this.dataSource.sort = this.sort;
}
}
export interface PeriodicElement {
name: string;
position: number;
weight: number;
symbol: string;
}
const ELEMENT_DATA: PeriodicElement[] = [
{position: 1, name: 'Hydrogen', weight: 1.0079, symbol: 'H'},
{position: 2, name: 'Helium', weight: 4.0026, symbol: 'He'},
{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'},
];

在您的HTML中将
<table>替换为<mat-table #table>. 这将解决您的错误 .
