极客教程Angular PrimeNG表过滤器
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。在这篇文章中，我们将看到如何在Angular PrimeNG中使用表过滤功能。
Angular PrimeNG Table Filter在Table组件中启用了Filter选项。因此，使用Filter选项，我们可以根据我们的需要轻松地搜索和过滤出所需的数据。
语法:
<p-table #tableref>
<ng-template pTemplate="caption">
<input
type="text"
pInputText
(input)="tableref.filterGlobal(
$event.target.value, 'contains')" />
</ng-template>
</p-table>
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表过滤器的使用，我们使用的是单列过滤。

<h4>Angular PrimeNG Table Filter</h4>
<p-table #myTab [value]="tableData"

"myTab.filter($event.target.value, col.field, col.filterMatchMode)" />
