前言

父向子传值（父组件通过属性传值给子组件，子组件通过@input方式来接受）\

父组件
<app-parent [data]="data"></app-parent>

子组件
<app-child></app-child> 
  @Input('data')

子向父传值（子组件通过@Output方式发出，父组件通过属性方式接受）

子组件
<app-child></app-child>
 //创建一个事件发射器
@Output() add = new EventEmitter();
 
父组件(属性接受)
<app-parent [add]="getData($event)"></app-parent>

一、创建table组件(子组件)

ng g c custom-table

custom-table.component.html

<nz-table #basicTable [nzData]="listOfData">
  <thead>
    <tr>
      <th>Name</th>
      <th>Age</th>
      <th>Address</th>
      <th>Action</th>
    </tr>
  </thead>
  <tbody>
    <tr *ngFor="let data of basicTable.data">
      <td>{{ data.name }}</td>
      <td>{{ data.age }}</td>
      <td>{{ data.address }}</td>
      <td nzAlign="center">
        <a (click)="editalertrule(data)">编辑</a>
        <nz-divider nzType="vertical"></nz-divider>
        <a (click)="delalertrule(data.id)">删除</a>
      </td>
    </tr>
  </tbody>
</nz-table>

custom-table.component.ts

import { Component, EventEmitter, Input, OnInit, Output } from '@angular/core';

@Component({
  selector: 'app-custom-table',
  templateUrl: './custom-table.component.html',
  styles: []
})
export class CustomTableComponent implements OnInit {

  @Input() listOfData;
  @Output() editRow = new EventEmitter()

  constructor() { }

  ngOnInit() {
  }

  editalertrule(data) {
    this.editRow.emit(data)
  }

}

二、父组件中调用table子组件

<app-custom-table [listOfData]="tableData" (editRow)="edit($event)"></app-custom-table>

import { Component, OnInit } from '@angular/core';

interface Person {
  key: string,
  name: string,
  age: number,
  address: string
}

@Component({
  selector: 'app-test',
  templateUrl: './test.component.html',
  styles: []
})
export class TestComponent implements OnInit {

  tableData: Person[] = [
    {
      key: '1',
      name: 'John Brown',
      age: 32,
      address: 'New York No. 1 Lake Park'
    },
    {
      key: '2',
      name: 'Jim Green',
      age: 42,
      address: 'London No. 1 Lake Park'
    },
    {
      key: '3',
      name: 'Joe Black',
      age: 32,
      address: 'Sidney No. 1 Lake Park'
    }
  ];


  constructor() { }

  edit(e) {
    console.log('e', e);
  }

}
