NullInjectorError:没有InjectionToken _ViewRepeater的提供者

嗨，我在从自定义ngModule创建表时遇到了以下错误，
问题：
- 无法理解错误的意思。
- 模块在其他地方工作，所以很可能是我错过了可能是
的东西。
ERROR Error: Uncaught (in promise): NullInjectorError: R3InjectorError(ProjectsModule)[InjectionToken _ViewRepeater -> InjectionToken _ViewRepeater -> InjectionToken _ViewRepeater -> InjectionToken _ViewRepeater]:
NullInjectorError: No provider for InjectionToken _ViewRepeater!

<table cng-table></tablecomponent.ts
import { Component, OnInit } from '@angular/core';
import { ActivatedRoute } from '@angular/router';
import { ConfigurationGroup } from 'src/app/interfaces/configurationGroup';
@Component({
selector: 'app-configuration',
templateUrl: './configuration.component.html',
styleUrls: ['./configuration.component.css']
})
export class ConfigurationComponent implements OnInit {
public routeParams!: Object;
public configurationGroups!: ConfigurationGroup[];
constructor(private route: ActivatedRoute) {
fetch('../assets/names.json')
.then(response => response.text())
.then(data => {
this.configurationGroups = JSON.parse(data);
});
}
ngOnInit(): void {
this.routeParams = this.route.snapshot.params;
}}
module.ts插入了cng-table模块，但是它的代码很长，而且对其他组件也很好。

尝尝这个。
@Component({
selector: 'app-configuration',
templateUrl: './configuration.component.html',
styleUrls: ['./configuration.component.css'],
providers: [
{provide: _VIEW_REPEATER_STRATEGY, useClass: _DisposeViewRepeaterStrategy},
{provide: _COALESCED_STYLE_SCHEDULER, useClass: _CoalescedStyleScheduler}
],
