如何在 prime ng 中为 angular2 应用程序提供内联编辑和删除按钮以及新按钮

Question

我有一个页面，它只有一个用户的东西。但是现在我必须创建一个 table 并且我需要获取数据，因此在 table 中我必须内联编辑和删除按钮。如果我单击编辑按钮，那么我必须能够编辑整行，删除意味着必须删除整行。当我单击“新建”按钮时，它必须为我创建一个包含编辑和删除操作的新行。我需要使用 ng-prime 本身来执行此操作。那么，任何人都可以帮助我提供链接或任何演示。

你可以使用[editable]="true"

来自Official Documentation reference：

Incell editing is enabled by setting editable property true both on datatable and columns. Clicking a cell switches to edit mode and hitting enter key or clicking another cell switches it back to view mode.

分量：

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

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {

  data: any = [];
  delRow;

  editRow(row) {
        this.data.filter(row => row.isEditable).map(r => { r.isEditable = false; return r })
    row.isEditable = true;
  }

  save(row){
    row.isEditable = false
  }

  addNew(){
    this.data.push({
      name: '',
      value: ''
    })
  }

  delete(row){
      console.log(row);
      this.delRow = this.data.indexOf(row);
      this.data.splice(this.delRow,1);
      console.log(this.data);

  }

  getData() {    
    this.data = [
      {name: "Name1", value: "value1"},
      {name: "Name2", value: "value2"},
      {name: "Name3", value: "value3"},
      {name: "Name4", value: "value4"}
      ];
      this.data.map(row => {      
        row.isEditable = false;        
      });    

  };


}

HTML:

 <button (click)="getData()">Load Data</button>
<button (click)="addNew()">Add New</button>

<p-dataTable [immutable]="false" [value]="data" [editable]="true">
    <p-column field="name" header="Name">
      <ng-template let-row="rowData" pTemplate="body">
        <div *ngIf="!row.isEditable">{{row.name}}</div>
        <div *ngIf="row.isEditable">
          <input type="text" [(ngModel)]="row.name">
        </div>
    </ng-template>
    </p-column>
    <p-column field="value" header="Value">
      <ng-template let-row="rowData" pTemplate="body">
        <div *ngIf="!row.isEditable">{{row.value}}</div>
        <div *ngIf="row.isEditable">
          <input type="text" [(ngModel)]="row.value">
        </div>
    </ng-template></p-column>    

    <p-column field="" header="" [style]="{'text-align':'center'}">
      <ng-template let-row="rowData" pTemplate="body">
        <button (click)="editRow(row)">Edit</button>
      </ng-template>
    </p-column>
    <p-column field="" header="" [style]="{'text-align':'center'}">
      <ng-template let-row="rowData" pTemplate="body">
        <button (click)="save(row)">Save</button>
      </ng-template>

    </p-column>
     <p-column field="" header="" [style]="{'text-align':'center'}">
      <ng-template let-row="rowData" pTemplate="body">
        <button (click)="delete(row)">Delete</button>
      </ng-template>


    </p-column>
</p-dataTable>
