极客教程Angular PrimeNG表全局过滤
Angular PrimeNG是一个开源框架，拥有丰富的原生Angular UI组件，可用于出色的造型，这个框架用于制作响应式网站，非常方便。这篇文章将告诉我们如何在Angular PrimeNG中使用表全局过滤。
Angular PrimeNG表全局过滤功能在表组件中启用了全局过滤选项。因此，使用全局过滤选项，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。我们使用表的filterGlobal方法，用值和匹配模式来实现表的全局过滤。
语法:
<p-table
#tableref
[globalFilterFields]="["...", "..."]">
<ng-template pTemplate="caption">
<input
type="text"
pInputText
(input)="tableref.filterGlobal(
any(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表全局过滤的使用。

<h4>Angular PrimeNG Table Global Filtering</h4>
<p-table

例子2：下面是另一个例子，演示Angular PrimeNG表全局过滤的使用。在这个例子中，我们从全局过滤字段中删除了姓氏，也就是说，如果我们使用姓氏列的值来过滤表格，它将不起作用。
