Angular 如何在一个组件中有多个Mat Paginator实例？

我不得不重新调整存放Mat Table/Mat Paginator的组件，因为我的HTML文件有一个ngIf。熟悉的人会知道Mat Paginator不符合处理Paginator的标准约定，因为数据到达需要时间。在下面，您可以找到当一个表使用mat分页时工作的更新类型脚本

现在，我需要在同一个组件中有两个具有Mat分页的表。然而，我只能得到一个工作。由于我是个新手，我希望有人能帮我指出正确的方向。随着我继续做更多的研究，我将更新我的问题。但据我所知，每个组件只能有一个Mat分页实例

您可以在下面找到工作的Typescript代码：

 dataSource1 = new MatTableDataSource<any>(this.userData());
 dataSource2 = new MatTableDataSource<any>(this.userData2());

 private paginator: MatPaginator;

  @ViewChild(MatPaginator, { static: false }) set matPaginator(mp: MatPaginator) {
    this.paginator = mp;
    this.dataSource1.paginator = this.paginator;
  }

ngOnInit() {
    this.dataSource1.paginator = this.paginator;
  }

dataSource1=newmattabledatasource（this.userData（））；
dataSource2=新MatTableDataSource（this.userData2（））；
私人分页者：MatPaginator；
@ViewChild（MatPaginator，{static:false}）集合MatPaginator（mp:MatPaginator）{
this.paginator=mp；
this.dataSource1.paginator=this.paginator；
}
恩戈尼尼特（）{
this.dataSource1.paginator=this.paginator；
}

---

最后，我希望分页对dataSource1和dataSource2起作用。显然，当我在ngOnInit和ViewChild中声明this.dataSource2.paginator=this.paginator时，它会中断这两者的分页。我已经验证了我的HTML是否正常。

我对使用相同分页器的两个表没有任何问题，我遵循angular docs指南并看到了它的工作原理：

ts文件：

import { Component, OnInit, ViewChild } from '@angular/core';
import {PageEvent, MatPaginator} from '@angular/material/paginator';
import { MatTableDataSource } from '@angular/material/table';

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'},
];

const ELEMENT_DATA2: PeriodicElement[] = [
  {position: 1, name: 'Neon', weight: 20.1797, symbol: 'Ne'},
  {position: 2, name: 'Fluorine', weight: 18.9984, symbol: 'F'},
  {position: 3, name: 'Oxygen', weight: 15.9994, symbol: 'O'},
  {position: 4, name: 'Nitrogen', weight: 14.0067, symbol: 'N'},
  {position: 5, name: 'Carbon', weight: 12.0107, symbol: 'C'},
  {position: 6, name: 'Boron', weight: 10.811, symbol: 'B'},
  {position: 7, name: 'Beryllium', weight: 9.0122, symbol: 'Be'},
  {position: 8, name: 'Lithium', weight: 6.941, symbol: 'Li'},
  {position: 9, name: 'Helium', weight: 4.0026, symbol: 'He'},
  {position: 10, name: 'Hydrogen', weight: 1.0079, symbol: 'H'},
];

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit{
  title = 'bootstrapDivTextInside';
  displayedColumns: string[] = ['position', 'name', 'weight', 'symbol'];
  dataSource = new MatTableDataSource<PeriodicElement>(ELEMENT_DATA);
  dataSource2 = new MatTableDataSource<PeriodicElement>(ELEMENT_DATA2);
  length = 100;
  pageSize = 2;
  pageSizeOptions: number[] = [5, 10, 25, 100];
  pageEvent: PageEvent;
  @ViewChild(MatPaginator, {static: true}) paginator: MatPaginator;

  constructor() {}

  ngOnInit() {
    this.dataSource.paginator = this.paginator;
    this.dataSource2.paginator = this.paginator;
  }

}

请提供您尝试的代码。我发现对多个MatDatasource实例使用相同的分页器没有问题，即使是在同一个组件中？当我尝试声明它时，两个表的分页都会中断。我将在几分钟内提供代码，即使在同一个组件中也是可行的，但是我必须为MatPaginator定义VIewChild的方式又如何呢？那么，def有什么问题吗？数据源不会加载到表中，除非我以这种方式定义VIewChild。我将直接抛出代码，您可以使用该结构创建一个空对象，然后当您承诺解析更新对象P.D:stackblitz被默认抛出到admin文件夹中的唯一组件中
