【问题描述】：

我有一个 Angular10 组件（切换开关），我需要将它包含在我的 ag-grid（单元格）的特定列中。

目前我有一个标准的 html 复选框，如下所示：

colDefs: ColDef[] = [
    { field: 'Name',             headerName: 'Name'},
    { field: 'Somethingelse',    headerName: 'Something else'},
    { field: 'Checkbox',         headerName: 'A Checkbox',      //<--this one
        editable:true,    
        checkboxSelection: false,   
        headerCheckboxSelection: false,   
        filter: false,    
        sortable: false,    
        cellRenderer: function (params: { value: boolean; }) {. //<--draws this
          var input = document.createElement("input");
          input.type = "checkbox";
          input.checked = params.value;
          return input;            //<--want to draw my component here instead
    } }
  ];

我想使用的组件而不是复选框已经存在于我的项目中：

import { Component, OnInit } from '@angular/core';
@Component({
  selector: 'my-toggle-switch',
  templateUrl: './toggle-switch.component.html',
  styleUrls: ['./toggle-switch.component.scss']
})
export class ToggleSwitchComponent implements OnInit {
  selected: boolean = false;
  constructor() { }
  ngOnInit(): void {}
}

如何包含 Angular10 组件来代替复选框？

【解决方案1】：

首先在 AG Grid 组件文件中导入您的组件。

import { ToggleSwitchComponent } from './ToggleSwitchComponent '; // whatever is the path

在coldef 中排名第二，只需将您的渲染器分配给cellRenderer

  { 
        field: 'Checkbox',
        headerName: 'A Checkbox',
        editable:true,    
        checkboxSelection: false,   
        headerCheckboxSelection: false,   
        filter: false,    
        sortable: false,    
        cellRenderer: 'ToggleSwitchComponent'
    } }

第三次在frameworkComponents下注册你的组件

 this.frameworkComponents = {
      ToggleSwitchComponent: ToggleSwitchComponent,
...
...
}

这就是渲染自定义组件所需的全部内容。

Few custom classes you need to add as per your need. Hope you can customize it by yourself. If you need all files let me  know I will send you generic files.  

<table class="table table-bordered table-hover">
        <thead>
          <tr>
            <th width="2%"></th>
            <th width="20%">Rule Name</th>
            <th width="10%">Rule ID</th>
          </tr>
        </thead>
        <tbody>
          <tr *ngFor="let item of gridItems">
            <td width="2%">
             <generic-checkbox [chkbxoptid]="'ruleId'"
              [data]="item.ruleInfo"
              ></generic-checkbox>
            </td>
            <td width="20%">{{item.ruleInfo.ruleName}}</td>
            <td width="10%">{{item.ruleInfo.ruleId}}</td>
          </tr>
        </tbody>
      </table>
    
    
    genericcomponent.ts

          // prevent memory leak when component destroyed
          this._subscription.unsubscribe();
