我正在使用Angular 7.0.2,并且在尝试使用Angular Material创建表时遇到此错误
由于它不是'mat-table'的已知属性,因此无法绑定到'dataSource'
app-routing.module.ts
import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { HttpClientModule } from '@angular/common/http';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { MatTableModule } from '@angular/material';
import { HomeComponent } from './home/home.component';
import { ProductionOrderComponent } from './production-order/production-order.component';
const routes: Routes = [
{ path: '', component: HomeComponent },
{ path: 'production-order', component: ProductionOrderComponent },
];
@NgModule({
imports: [
RouterModule.forRoot(routes),
HttpClientModule,
BrowserAnimationsModule,
MatTableModule,
],
exports: [RouterModule]
})
export class AppRoutingModule { }
html
<mat-table [dataSource]="productionOrder" class="mat-elevation-z8">
<ng-container matColumnDef="t_pdno">
<th mat-header-cell *matHeaderCellDef>Production Order</th>
<td mat-cell *matCellDef="let productionOrder">{{ productionOrder.t_pdno }}</td>
</ng-container>
<ng-container matColumnDef="t_mitm">
<th mat-header-cell *matHeaderCellDef>Item</th>
<td mat-cell *matCellDef="let productionOrder">{{ productionOrder.t_mitm }}</td>
</ng-container>
<mat-header-row *matHeaderRowDef="['t_pdno', 't_mitm']"></mat-header-row>
<mat-row *matRowDef="let row; columns: ['t_pdno', 't_mitm'];"></mat-row>
</mat-table>
组件
import { Component, OnInit } from '@angular/core';
import { HttpClient } from '@angular/common/http';
@Component({
selector: 'app-production-order',
templateUrl: './production-order.component.html',
styleUrls: ['./production-order.component.scss']
})
export class ProductionOrderComponent implements OnInit {
public productionOrder
constructor(private http: HttpClient) { }
ngOnInit() {
this.getData()
}
getData() {
this.http.get('http://localhost:3000/api/production-order').subscribe(res => {
console.log(res['data'])
this.productionOrder = res['data']
})
}
}
我尝试过的事情:
使用<table mat-table>
代替<mat-table>
import { MatTableModule } from '@angular/material';
以及这些链接:
Can't bind to 'dataSource' since it isn't a known property of 'table'
mat-table can't bind dataSource
有人知道如何解决这个问题吗?

您应该在MatTableModule
或声明组件的模块中导入AppModule
。
@NgModule({
imports: [
MatTableModule
...
]
})
public class AppModule
或
@NgModule({
imports: [
MatTableModule
...
],
declarations : [ProductionOrderComponent]
})
public class MyModule

我想完成Sunil的回答:您应该在MatTableModule
或声明组件的模块中导入CdkTableModule
和AppModule
。
@NgModule({
imports: [
CdkTableModule,
MatTableModule
...
]
})
public class AppModule

如果您认为通过在如下所示的app.module.ts中导入 MatTableModule 可以正确地完成所有操作
2^3
,然后在html上将
