极客教程Angular PrimeNG Table Flexscroll
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。本文将向我们展示如何在Angular PrimeNG中使用Table Flex Scroll。
Angular PrimeNG Table Flexscroll在Table组件中启用Flex Scroller。在视口应该根据表父的高度而不是固定的视口高度进行自我调整的情况下，将scrollHeight选项设置为flex。因此，使用柔性滚动，我们可以很容易地定制表组件，并根据最佳的用户体验来显示表数据。
语法:
<p-table
[scrollable]="true"
scrollHeight='flex'
>
</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 Table Flex Scroll的使用。
<div class="page-content"
style="height: calc(100vh - 149px)">
