Angular PrimeNG表列分组

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，非常容易。本文将告诉我们如何在Angular PrimeNG中使用表列分组。

Angular PrimeNG Table Sections提供各种模板来显示数据的额外信息，如标题或摘要。

语法:

<ng-template pTemplate="caption">
    Captions
</ng-template>
<ng-template pTemplate="summary">
    Summary
</ng-template>

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 Sections的使用。在这个例子中，我们使用的是一个标题模板。
