StaticInjectorErro(AppModule) [ScrollableView -> Table]: table 没有提供者

Question

我正在为我的项目使用 primeng 组件。我想使用 table 组件，但我不得不对 table 组件的模板进行一些更改。所以我制作了一个扩展 primeng Table class 的新组件。然后有一些关于 ptablebody 和 pscrollableview classes 的错误，我发现这两个组件没有在 primeng TableModule 中声明和导出，所以我将它们添加到 declarations 和 exports 文件中的数组 node_modules/primeng/components/table/table.js。在那之后有这个错误：

这是我的自定义 table 组件的代码：table.component.ts

import {Component, ElementRef,  NgZone} from '@angular/core';
    import { CommonModule } from '@angular/common';
    import {Table , TableService } from 'primeng/components/table/table';
    import { DomHandler } from 'primeng/components/dom/domhandler';
    import { ObjectUtils } from 'primeng/components/utils/objectutils';
    import { Subject, Subscription } from 'rxjs';
@Component({
    selector: 'app-custom-table',
    template: `
        <div #container [ngStyle]="style" [class]="styleClass"
            [ngClass]="{'ui-table ui-widget': true, 'ui-table-responsive': responsive, 'ui-table-resizable': resizableColumns,
                'ui-table-resizable-fit': (resizableColumns && columnResizeMode === 'fit'),
                'ui-table-hoverable-rows': (rowHover||selectionMode), 'ui-table-auto-layout': autoLayout}">

        </div>
    `,
    providers: [DomHandler, ObjectUtils, TableService]
})
export class CustomTableComponent extends Table{

    constructor(public el: ElementRef, 
        public domHandler: DomHandler, 
        public objectUtils: ObjectUtils, 
        public zone: NgZone, 
        public tableService: TableService) {
            super(el , domHandler . objectUtils , zone, tableService);
        }

}

这里是错误

ERROR Error: StaticInjectorError(AppModule)[ScrollableView -> Table]: Static InjectorError(Platform: core)[ScrollableView -> Table]: NullInjectorEro: No Provider for Table! ...

ERROR Error: StaticInjectorError(AppModule)[TableBody -> Table]: Static InjectorError(Platform: core)[TableBody -> Table]: NullInjectorEro: No Provider for Table! ...

你知道我该如何解决这个问题吗？

Answer 1

我刚刚解决了它。我应该将 table 添加到供应商数组。

StaticInjectorErro(AppModule) [ScrollableView -> Table]: table 没有提供者
