Getting Started(入门)

数据表需要一个数组作为值对象和列p-column组件定义。在整个样本,汽车接口具有VIN,品牌,年份和颜色属性是用来定义一个对象是由数据表中显示。汽车是由一个carservice连接到服务器去取车的Promise.

export interface Car {
vin;
year;
brand;
color;
}
import {Injectable} from 'angular2/core';
import {Http, Response} from 'angular2/http';
import {Car} from '../domain/car'; @Injectable()
export class CarService { constructor(private http: Http) {} getCarsSmall() {
return this.http.get('/showcase/resources/data/cars-small.json')
.toPromise()
.then(res => <Car[]> res.json().data)
.then(data => { return data; });
}
}

下面的示例数据表有4列,从服务检索数据的初始化。

export class DataTableDemo implements OnInit {

    cars: Car[];

    constructor(private carService: CarService) { }

    ngOnInit() {
this.carService.getCarsSmall().then(cars => this.cars = cars);
}
}

汽车列表绑定到值的属性和列使用p-column组件定义。

<p-dataTable [value]="cars">
<p-column field="vin" header="Vin"></p-column>
<p-column field="year" header="Year"></p-column>
<p-column field="brand" header="Brand"></p-column>
<p-column field="color" header="Color"></p-column>
</p-dataTable>

Column Component

列组件定义了各种选项以指定相应的功能。

<p-column field="vin" header="Vin" [sortable]="true"></p-column>

Dynamic Colums

列可以被实例化使用数组以及ngfor迭代。

export class DataTableDemo implements OnInit {

    cars: Car[];

    cols: any[];

    constructor(private carService: CarService) { }

    ngOnInit() {
this.carService.getCarsSmall().then(cars => this.cars = cars); this.cols = [
{field: 'vin', header: 'Vin'},
{field: 'year', header: 'Year'},
{field: 'brand', header: 'Brand'},
{field: 'color', header: 'Color'}
];
}
}
<p-dataTable [value]="cars">
<p-column *ngFor="let col of cols" [field]="col.field" [header]="col.header"></p-column>
</p-dataTable>

Templates

一个相应的行字段的数据显示为默认的单元格的内容,可以自定义模板,使用隐式变量传递到ng模板列定义和当前行数据rowData财产。在目前除了指数可以使用可选的rowIndex变量访问。类似地,自定义内容可以放在列的页眉和页脚上,模板。

ng-template内的列必须用ptemplate指令来表明ng-template属于的类型。可能的值是“头”、“体”和“页脚”。

<p-column field="color" header="Color">
<ng-template let-col let-car="rowData" let-ri="rowIndex" pTemplate="body">
<span>{{car[col.field]}}</span>
</ng-template>
</p-column>
<p-column>
<ng-template pTemplate="header">
<button type="button" pButton (click)="selectAllCars()" icon="fa-check"></button>
</ng-template>
<ng-template let-car="rowData" pTemplate="body">
<button type="button" pButton (click)="selectCar(car)" icon="fa-search"></button>
</ng-template>
</p-column>

行的索引在ng-template可用。

 <p-column>
<ng-template let-car="rowData" let-i="rowIndex" pTemplate="body">
<button type="button" pButton (click)="selectCar(i)" icon="fa-search"></button>
</ng-template>
</p-column>

example

Facets

页眉和页脚是可以显示自定义内容的两个部分。

import {Header} from 'primeng/primeng';
import {Footer} from 'primeng/primeng';
<p-dataTable [value]="cars">
<p-header>List of Cars</p-header>
<p-footer>Choose from the list.</p-footer>
<p-column field="vin" header="Vin"></p-column>
<p-column field="year" header="Year"></p-column>
<p-column field="brand" header="Brand"></p-column>
<p-column field="color" header="Color"></p-column>
</p-dataTable>

Column Grouping

列可以被分组在页眉和页脚使用headercolumngroup和footercolumngroup组件包含行与列。模板也支持内分组列。

<p-dataTable [value]="sales">
<p-headerColumnGroup>
<p-row>
<p-column header="Brand" rowspan="3"></p-column>
<p-column header="Sale Rate" colspan="4"></p-column>
</p-row>
<p-row>
<p-column header="Sales" colspan="2"></p-column>
<p-column header="Profits" colspan="2"></p-column>
</p-row>
<p-row>
<p-column header="Last Year"></p-column>
<p-column header="This Year"></p-column>
<p-column header="Last Year"></p-column>
<p-column header="This Year"></p-column>
</p-row>
</p-headerColumnGroup> <p-column field="brand"></p-column>
<p-column field="lastYearSale"></p-column>
<p-column field="thisYearSale"></p-column>
<p-column field="lastYearProfit"></p-column>
<p-column field="thisYearProfit"></p-column> <p-footerColumnGroup>
<p-row>
<p-column footer="Totals:" colspan="3"></p-column>
<p-column footer="$506,202"></p-column>
<p-column footer="$531,020"></p-column>
</p-row>
</p-footerColumnGroup>
</p-dataTable>

Row Grouping

行可以按一个单独的分组的行或使用的行。在这两种情况下,数据必须由分组字段首先进行排序。

<p-dataTable [value]="cars1" sortField="brand" rowGroupMode="subheader" groupField="brand">
<p-header>Subheader</p-header>
<ng-template pTemplate="rowgroupheader" let-rowData>{{rowData['brand']}}</ng-template>
<p-column field="color" header="Color"></p-column>
<p-column field="year" header="Year"></p-column>
<p-column field="vin" header="Vin"></p-column>
</p-dataTable> <p-dataTable [value]="cars2" sortField="brand" rowGroupMode="rowspan">
<p-header>RowSpan</p-header>
<p-column field="brand" header="Brand"></p-column>
<p-column field="color" header="Color"></p-column>
<p-column field="year" header="Year"></p-column>
<p-column field="vin" header="Vin"></p-column>
</p-dataTable>

一组知名度可切换使用的图标放在旁边,用expandablerowgroups属性组的名称。默认情况下,所有的组都崩溃了,expandadrowgroups财产需要填充组字段值显示特定群体扩展默认。

<p-dataTable [value]="cars" sortField="brand" rowGroupMode="subheader" groupField="brand" expandableRowGroups="true">
<p-header>Subheader</p-header>
<ng-template pTemplate="rowgroup" let-rowData>{{rowData['brand']}}</ng-template>
<p-column field="color" header="Color"></p-column>
<p-column field="year" header="Year"></p-column>
<p-column field="vin" header="Vin"></p-column>
</p-dataTable>

一个排的页脚可以使用rowgroupfooter ng模板定义。

 <p-dataTable [value]="cars" sortField="brand" rowGroupMode="subheader" groupField="brand" expandableRowGroups="true"
[sortableRowGroup]="false">
<p-header>Toggleable Row Groups with Footers</p-header>
<ng-template pTemplate="rowgroupheader" let-rowData>{{rowData['brand']}}</ng-template>
<p-column field="color" header="Color"></p-column>
<p-column field="year" header="Year"></p-column>
<p-column field="vin" header="Vin"></p-column>
<p-column field="price" header="Price">
<ng-template let-col let-car="rowData" pTemplate="body">
<span>{{car[col.field] | currency:'USD':true:'.0-0'}}</span>
</ng-template>
</p-column>
<ng-template pTemplate="rowgroupfooter" let-car>
<td colspan="3" style="text-align:right">Total Price</td>
<td>{{calculateGroupTotal(car['brand']) | currency:'USD':true:'.0-0' }}</td>
</ng-template>
</p-dataTable>

单击行组分类根据组字段的数据,你可以使用sortablerowgroup财产这一行为控制

demo code

export class DataTableRowGroupDemo implements OnInit {

    cars1: Car[];

    cars2: Car[];

    cars3: Car[];

    constructor(private carService: CarService) {}

    ngOnInit() {
this.carService.getCarsMedium().then(cars => this.cars1 = cars);
this.carService.getCarsMedium().then(cars => this.cars2 = cars);
this.carService.getCarsMedium().then(cars => this.cars3 = cars);
} calculateGroupTotal(brand: string) {
let total = 0; if(this.cars1) {
for(let car of this.cars1) {
if(car.brand === brand) {
total += car.price;
}
}
} return total;
}
}

Paginator

分页的设置页面属性来启用,行属性定义每个页面的行数和页面连接,指定要显示的数页链接。

<p-dataTable [value]="cars" [rows]="10" [paginator]="true">
<p-column field="vin" header="Vin"></p-column>
<p-column field="year" header="Year"></p-column>
<p-column field="brand" header="Brand"></p-column>
<p-column field="color" header="Color"></p-column>
</p-dataTable>

demo code

export class DataTablePaginatorDemo implements OnInit {

    cars: Car[];

    constructor(private carService: CarService) { }

    ngOnInit() {
this.carService.getCarsMedium().then(cars => this.cars = cars);
}
}

<p-column field="vin" header="Vin"></p-column>
<p-column field="year" header="Year"></p-column>
<p-column field="brand" header="Brand"></p-column>
<p-column field="color" header="Color"></p-column>
</p-dataTable>

Sorting

简单使列对象排序的性能足以让一列排序。属性时要使用的默认排序字段,可以使用sortfield定制。

<p-column field="vin" header="Vin" sortable="true"></p-column>

默认情况下,在单击列执行排序。做的多字段分类,设置“多”SortMode属性和使用元键点击另一列。

<p-dataTable [value]="cars" [sortMode]="multiple">

如果你想显示表按默认最初的负载,使用单一模式的sortfield SortOrder属性。

<p-dataTable [value]="cars" sortField="year" [sortOrder]="1">
<p-column field="vin" header="Vin" sortable="true"></p-column>
<p-column field="year" header="Year" sortable="true"></p-column>
<p-column field="brand" header="Brand" sortable="true"></p-column>
<p-column field="color" header="Color" sortable="true"></p-column>
</p-dataTable>

在multiple mode,使用multisortmeta属性和约束sortmeta对象数组。在多个模式,使用multisortmeta属性和约束sortmeta对象数组。

<p-dataTable [value]="cars" [multiSortMeta]="multiSortMeta">
<p-column field="vin" header="Vin" sortable="true"></p-column>
<p-column field="year" header="Year" sortable="true"></p-column>
<p-column field="brand" header="Brand" sortable="true"></p-column>
<p-column field="color" header="Color" sortable="true"></p-column>
</p-dataTable>
this.multiSortMeta = [];
this.multiSortMeta.push({field: 'year', order: 1});
this.multiSortMeta.push({field: 'brand', order: -1});

自定义排序,将排序选项,自定义,定义一个sortfunction分类列表。

<p-dataTable [value]="cars" [multiSortMeta]="multiSortMeta">
<p-column field="vin" header="Vin" sortable="true"></p-column>
<p-column field="year" header="Year" sortable="custom" (sortFunction)="mysort($event)"></p-column>
<p-column field="brand" header="Brand" sortable="true"></p-column>
<p-column field="color" header="Color" sortable="true"></p-column>
</p-dataTable>
mysort(event) {
//event.field = Field to sort
//event.order = Sort order
}

demo code

export class DataTableSortDemo implements OnInit {

    cars1: Car[];

    cars2: Car[];

    constructor(private carService: CarService) { }

    ngOnInit() {
this.carService.getCarsSmall().then(cars => this.cars1 = cars);
this.carService.getCarsSmall().then(cars => this.cars2 = cars);
}
}

<p-column field="color" header="Color" [sortable]="true"></p-column>
</p-dataTable>

Filtering

通过在列上设置筛选器属性为True,启用了筛选。默认的匹配模式是“startsWith”,这可以被配置为使用filtermatchmode属性,也接受"contains", "endsWith", "equals" and "in"。

<p-column field="vin" header="Vin (startsWith)" [filter]="true" filterPlaceholder="Search"></p-column>
<p-column field="year" header="Year (contains)" [filter]="true" filterMatchMode="contains"></p-column>
<p-column field="brand" header="Brand (startsWith)" [filter]="true"></p-column>
<p-column field="color" header="Color (endsWith)" [filter]="true" filterMatchMode="endsWith"></p-column>

一个可选的全球过滤功能可与相同的关键字搜索的所有领域,使这个地方输入组件的KeyUp事件会听了过滤和绑定的局部ng模板变量名为全球的滤波特性。

<input #gb type="text" placeholder="Global search">
<p-dataTable [value]="cars" [rows]="10" [globalFilter]="gb">

默认情况下,输入字段用作过滤器元素,并且可以使用模板进行自定义。它是用在过滤元件改变回调通过值调用DataTable的过滤方法重要,场和matchmode性质。

<p-column field="brand" header="Brand (Custom)" [filter]="true" [style]="{'overflow':'visible'}" filterMatchMode="equals">
<ng-template pTemplate="filter" let-col>
<p-dropdown [options]="brands" [style]="{'width':'100%'}" (onChange)="dt.filter($event.value,col.field,col.filterMatchMode)" styleClass="ui-column-filter"></p-dropdown>
</ng-template>
</p-column>

demo code

export class DataTableFilterDemo implements OnInit {

    cars: Car[];

    brands: SelectItem[];

    colors: SelectItem[];

    constructor(private carService: CarService) {}

    ngOnInit() {
this.carService.getCarsMedium().then(cars => this.cars = cars); this.brands = [];
this.brands.push({label: 'All Brands', value: null});
this.brands.push({label: 'Audi', value: 'Audi'});

Selection

DataTable提供一排点击单个和多个模式的选择。选定行必然选择属性和onrowselect onrowunselect事件提供了可选的回调。另外基于列的选择可以使用单选按钮或复选框使用一个特定的列SelectionMode为。比较时,如果一行被选中,DataTable穿越影响性能结果的对象的所有属性。建议定义一个DataKey属性唯一标识一个记录,避免深对象比较和提高性能。

在单一模式下,选择绑定是一个对象引用。

export class DataTableDemo implements OnInit {

    cars: Car[];

    selectedCar: Car;

    constructor(private carService: CarService) { }

    ngOnInit() {
this.carService.getCarsSmall().then(cars => this.cars = cars);
}
}
<p-dataTable [value]="cars" selectionMode="single" [(selection)]="selectedCar" dataKey="vin">
<p-column field="vin" header="Vin"></p-column>
<p-column field="year" header="Year"></p-column>
<p-column field="brand" header="Brand"></p-column>
<p-column field="color" header="Color"></p-column>
</p-dataTable>

在多模式选择的结合应该是一个数组和多个项目可以选择使用元键或切换单独依靠metakeyselection属性值是真正的默认值。触摸功能的设备metakeyselection自动关闭。

export class DataTableDemo implements OnInit {

    cars: Car[];

    selectedCars: Car[];

    constructor(private carService: CarService) { }

    ngOnInit() {
this.carService.getCarsSmall().then(cars => this.cars = cars);
}
}
<p-dataTable [value]="cars" selectionMode="multiple" [(selection)]="selectedCars" dataKey="vin">
<p-column field="vin" header="Vin"></p-column>
<p-column field="year" header="Year"></p-column>
<p-column field="brand" header="Brand"></p-column>
<p-column field="color" header="Color"></p-column>
</p-dataTable>

如果你喜欢一个单选按钮或复选框,而不是连续点击,使用一列的SelectionMode为相反。以下数据表显示在每一行的第一列的复选框,复选框中自动添加一个标题行切换选择。

<p-dataTable [value]="cars" [(selection)]="selectedCars" dataKey="vin">
<p-column selectionMode="multiple"></p-column>
<p-column field="vin" header="Vin"></p-column>
<p-column field="year" header="Year"></p-column>
<p-column field="brand" header="Brand"></p-column>
<p-column field="color" header="Color"></p-column>
</p-dataTable>

ContextMenu

DataTable与ContextMenu独家整合。为了将一个菜单数据表,定义了一个局部的菜单模板变量并将其绑定到DataTable的ContextMenu属性。这使显示的菜单时,行右键单击。

<p-dataTable [value]="cars" selectionMode="single" [(selection)]="selectedCar" [contextMenu]="cm">
<p-header>Right Click on Rows for ContextMenu</p-header>
<p-column field="vin" header="Vin"></p-column>
<p-column field="year" header="Year"></p-column>
<p-column field="brand" header="Brand"></p-column>
<p-column field="color" header="Color"></p-column>
</p-dataTable> <p-contextMenu #cm [model]="items"></p-contextMenu>

Editing

Incell editing通过设置编辑属性编辑对DataTable和列真正启用。单击单元格切换到编辑模式,点击Enter键或单击另一个单元格将其切换回查看模式。

<p-dataTable [value]="cars" [editable]="true">
<p-column field="vin" header="Vin" [editable]="true"></p-column>
<p-column field="year" header="Year" [editable]="true"></p-column>
<p-column field="brand" header="Brand" [editable]="true"></p-column>
<p-column field="color" header="Color" [editable]="true"></p-column>
</p-dataTable>

简单的输入字段作为编辑元素默认情况下,这可以通过添加一个定制的ptemplate命名编辑。

<p-dataTable [value]="cars" [editable]="true">
<p-column field="vin" header="Vin" [editable]="true"></p-column>
<p-column field="year" header="Year" [editable]="true"></p-column>
<p-column field="brand" header="Brand" [editable]="true" [style]="{'overflow':'visible'}">
<ng-template let-col let-car="rowData" pTemplate="editor">
<p-dropdown [(ngModel)]="car[col.field]" [options]="brands" [autoWidth]="false" [style]="{'width':'100%'}" required="true"></p-dropdown>
</ng-template>
</p-column>
<p-column field="color" header="Color" [editable]="true"></p-column>
<p-column field="saleDate" header="Sale Date" [editable]="true" [style]=" {'overflow':'visible' }">
<ng-template let-col let-car="rowData" pTemplate="body">
{{car[col.field]|date }}
</ng-template>
<ng-template let-col let-car="rowData" pTemplate="editor">
<p-calendar [(ngModel)]="car[col.field]"></p-calendar>
</ng-template>
</p-column>
</p-dataTable>

Expandable Rows

行扩展允许显示特定行的详细内容。要使用此功能,使expandablerows属性,添加膨胀柱宣布扩大内容提供ptemplate“rowexpansion”为价值。

<p-dataTable [value]="cars" expandableRows="true">
<p-column expander="true" [style]="{'width':'22px'}"></p-column>
<p-column field="vin" header="Vin"></p-column>
<p-column field="year" header="Year"></p-column>
<p-column field="brand" header="Brand"></p-column>
<p-column field="color" header="Color"></p-column>
<ng-template let-car pTemplate="rowexpansion">
<div class="ui-grid ui-grid-responsive ui-fluid" style="font-size:16px;padding:20px">
<div class="ui-grid-row">
<div class="ui-grid-col-3" style="text-align:center">
<img src="showcase/resources/demo/images/car/{{car.brand}}-big.gif">
</div>
<div class="ui-grid-col-9">
<div class="ui-grid ui-grid-responsive ui-grid-pad">
<div class="ui-grid-row">
<div class="ui-grid-col-2 label">Vin: </div>
<div class="ui-grid-col-10">{{car.vin}}</div>
</div>
<div class="ui-grid-row">
<div class="ui-grid-col-2 label">Year: </div>
<div class="ui-grid-col-10">{{car.year}}</div>
</div>
<div class="ui-grid-row">
<div class="ui-grid-col-2 label">Brand: </div>
<div class="ui-grid-col-10">{{car.brand}}</div>
</div>
<div class="ui-grid-row">
<div class="ui-grid-col-2 label">Color: </div>
<div class="ui-grid-col-10">{{car.color}}</div>
</div>
</div>
</div>
</div>
</div>
</ng-template>
</p-dataTable>

默认情况下所有行倒塌,expandadrows财产需要填充的行数据实例来显示特定行为扩展默认。

Column Resize

列的大小可以使用拖放设置resizablecolumns真实。有两个大小调整模式;"fit" and "expand"。"fit"是默认的和整体的桌子的宽度并没有改变时,一列大小。在"expand"模式下,表宽也随着列宽度的变化而变化。oncolumnresize回调是通过调整列标题作为参数。

<p-dataTable [value]="cars" [resizableColumns]="true">
<p-column field="vin" header="Vin"></p-column>
<p-column field="year" header="Year"></p-column>
<p-column field="brand" header="Brand"></p-column>
<p-column field="color" header="Color"></p-column>
</p-dataTable>

Data Export

DataTable可以以CSV格式的使用exportcsv()方法其数据输出。

<p-dataTable #dt [value]="cars">
<p-column field="vin" header="Vin"></p-column>
<p-column field="year" header="Year"></p-column>
<p-column field="brand" header="Brand"></p-column>
<p-column field="color" header="Color"></p-column>
</p-dataTable> <button type="button" pButton icon="fa-file-o" iconPos="left" label="CSV" (click)="dt.exportCSV()"></button>

Scrolling

DataTable支持水平和垂直滚动通过定义scrollwidth和scrollheight选项分别。属性可以采取固定像素值或百分比来计算滚动视图相对于DataTable母。样品使用垂直滚动,头下面是固定的,数据是可滚动的。在水平滚动,重要的是给固定宽度的列。

<p-dataTable [value]="cars" [scrollable]="true" scrollHeight="200px">
<p-column field="vin" header="Vin"></p-column>
<p-column field="year" header="Year"></p-column>
<p-column field="brand" header="Brand"></p-column>
<p-column field="color" header="Color"></p-column>
</p-dataTable>

在水平滚动中,通过在列级上启用冻结属性,可以固定某些列。

<p-dataTable [value]="cars" [scrollable]="true" scrollHeight="200px" frozenWidth="100px" scrollWidth="600px">
<p-column field="vin" header="Vin" frozen="true"></p-column>
<p-column field="year" header="Year"></p-column>
<p-column field="brand" header="Brand"></p-column>
<p-column field="color" header="Color"></p-column>
</p-dataTable>

此外,virtualscroll模式可以通过加载数据需求处理大型数据集时滚动。

Lazy Loading

懒模式是得心应手地处理大型数据集,而不是加载整个数据,小块数据是通过调用回调onlazyload每次分页加载,排序和过滤发生。实现懒加载,使懒惰的属性和提供利用onlazyload实际加载数据从远程数据源的方法回调。onlazyload获取一个事件对象包含有关如何负荷。它还指定行数的逻辑totalrecords做一个页面配置投影查询,页面显示UI假设实际上有记录totalrecords规模虽然在现实中他们没有在懒人模式重要,只显示当前页的记录存在。

<p-dataTable [value]="cars" [scrollable]="true" [lazy]="true" (onLazyLoad)="loadData($event)" [totalRecords]="totalRecords">
<p-column field="vin" header="Vin"></p-column>
<p-column field="year" header="Year"></p-column>
<p-column field="brand" header="Brand"></p-column>
<p-column field="color" header="Color"></p-column>
</p-dataTable>
loadData(event: LazyLoadEvent) {
//event.first = First row offset
//event.rows = Number of rows per page
//event.sortField = Field name to sort in single sort mode
//event.sortOrder = Sort order as number, 1 for asc and -1 for dec in single sort mode
//multiSortMeta: An array of SortMeta objects used in multiple columns sorting. Each SortMeta has field and order properties.
//filters: Filters object having field as key and filter value, filter matchMode as value
//globalFilter: Value of the global filter if available
this.cars = //do a request to a remote datasource using a service and return the cars that match the lazy load criteria
}

Responsive

数据表列显示为堆放在应答模式如果屏幕尺寸变得小于某个断点值。此功能启用响应设置为true。

<p-dataTable [value]="cars" [responsive]="true">
<p-column field="vin" header="Vin"></p-column>
<p-column field="year" header="Year"></p-column>
<p-column field="brand" header="Brand"></p-column>
<p-column field="color" header="Color"></p-column>
</p-dataTable>

Overlays in Cells

Cells of datatable隐藏溢出默认情况下,这可以防止一部分像下拉菜单可正常显示叠加。在这样的情况下,设置列的样式以允许溢出。

<p-column field="color" [style]="{'overflow':'visible'}">
<ng-template let-col let-car="rowData">
<p-dropdown></p-dropdown>
</ng-template>
</p-column>

Immutable Mode

使用diff检查如果DataTable来实现底层的数据发生了变化,这可能会降低性能,避免它一成不变的模式,确保您的数据的变化,如添加或删除一个记录都创建一个新数组引用。例如,添加项目时使用切片而不是剪接,添加项目时使用扩展运算符而不是推送方法。

Loading Status

DataTable具有承载性能,当启用旋转图标显示数据加载。

<p-dataTable [value]="cars" [loading]="loading">
<p-column field="vin" header="Vin"></p-column>
<p-column field="year" header="Year"></p-column>
<p-column field="brand" header="Brand"></p-column>
<p-column field="color" header="Color"></p-column>
</p-dataTable>
export class DataTableDemo implements OnInit {

    loading: boolean;

    cars: Car[];

    constructor(private carService: CarService) { }

    ngOnInit() {
this.loading = true;
setTimeout(() => {
this.carService.getCarsSmall().then(cars => this.cars = cars);
this.loading = false;
}, 1000);
}
}
