极客教程Angular PrimeNG表格编辑
Angular PrimeNG是一个开源框架，它有丰富的原生Angular UI组件，可以用来做很好的造型，这个框架用来做响应式网站，非常方便。本文将告诉我们如何在Angular PrimeNG中使用TreeTable Edit。
Angular PrimeNG Table Edit可以编辑Table组件中的Table单元。所以使用编辑功能，我们可以很容易地编辑表组件的数据。
语法:
<p-table>
<td pEditableColumn>
<p-cellEditor>
<ng-template pTemplate="input">
<input pInputText type="text"
[(ngModel)]="product.code" disabled>
</ng-template>
<ng-template pTemplate="output">
{{product.code}}
</ng-template>
</p-cellEditor>
</td>
</p-treeTable>
创建Angular应用程序和模块安装。
第1步：使用以下命令创建一个Angular应用程序。
ng new appname
第2步：创建你的项目文件夹即appname后，使用以下命令移动到它。
cd appname
第3步在你给定的目录中安装PrimeNG。
npm install primeng --save
npm install primeicons --save
项目结构：它将看起来像如下。
例子1：下面是一个简单的例子，演示Angular PrimeNG Table Edit的使用，我们必须使用p-treeTableCellEditor来使单元格可编辑。

<h4>Angular PrimeNG Table Edit</h4>
<p-table #myTab [value]="tableData"
[scrollable]="true"
[columns]="cols"
scrollHeight="400px">
<ng-template pTemplate="header">
<tr>
<th>First Name</th>
<th>Last Name</th>
<th>Age</th>
</tr>
</ng-template>
<ng-template pTemplate="body" let-people>

<td pEditableColumn>
<p-cellEditor>
<ng-template pTemplate="input">

[(ngModel)]="people.firstname" />

import { Component } from "@angular/core";
interface People {
firstname?: string;
lastname?: string;
age?: string;
}
@Component({
selector: "app-root",
templateUrl: "./app.component.html",
})
export class AppComponent {
tableData: People[] = [];
cols: any[] = [];
constructor() {}
ngOnInit() {
this.cols = [
{ field: "firstname", header: "First Name" },
{ field: "lastname", header: "Last Name" },
{ field: "age", header: "Age" },
];
this.tableData = [
{
firstname: "David",
lastname: "ace",
age: "40",

实例2：下面是另一个演示Angular PrimeNG Table Edit使用的例子。我们还可以使用disabled属性禁止编辑表格单元。
