Angular PrimeNG表的水平滚动

Angular PrimeNG是一个开源的库，由原生的Angular UI组件组成，用来做伟大的造型，这个框架用来制作响应式网站，非常容易。在这篇文章中，我们将看到Angular PrimeNG表的水平滚动。

表组件用于以表格的形式向用户显示一些数据。当表格超过视口的宽度时，可以通过设置scrollable属性为 “true “和scrollDirection属性为 “horizontal “来启用水平滚动，同时给列提供固定宽度。

语法:

<p-table [value]="cars" **[scrollable]="true"**
    **scrollDirection="horizontal"** >
    <ng-template pTemplate="header">
        <tr>
            <th style="width: 300px">Car</th>
            <th style="width: 300px">Company</th>
            <th style="width: 300px">Vehicle Number</th>
            ...
        </tr>
    </ng-template>
    <ng-template pTemplate="body" let-car>
        <tr>
            <td style="width: 300px">{{car.name}}</td>
            <td style="width: 300px">{{car.company}}</td>
            <td style="width: 300px">{{car.number}}</td>
            ...
        </tr>
    </ng-template>
</p-table>

创建Angular应用程序并安装模块：

第1步：使用以下命令创建一个Angular应用程序。

ng new myapp

第2步：创建你的项目文件夹即myapp后，使用以下命令移动到它。

cd myapp

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：完成上述步骤后，项目结构将如下所示。
