如何在< p-datatable>中使用模板 [英] How to use template in <p-datatable>

问题描述

我有一个非常基本的问题，我无法回答自己，因为大多数指向 http://www的链接.primefaces.org/primeng 不再起作用. 我也尝试注册到他们的论坛，但是他们的激活邮件从未到达.

I've got a very basic question which I can't answer myself because most links to http://www.primefaces.org/primeng don't work anymore. I also tried registering to their forum but their activation mail never arrives.

我使用Angular2，并且有一个包含两列的数据表:文件名和状态. 我要更改的状态列.它现在拥有一个从1到4的数字，我想根据状态显示一个glyphicon.

I use Angular2 and have a datatable with two columns: filename and status. The status column I want to change. It holds now a number from 1 to 4 and I want to show a glyphicon based on the status.

我现在有这个，它正在工作:

I now have this, which is working:

<p-dataTable [hidden]="loading" [value]="files" selectionMode="single"  sortField="Status" [sortOrder]="-1">
  <p-column field="FileName" header="Naam" sortable="true"></p-column>
  <p-column field="Status" header="Status" sortable="true"></p-column>
</p-dataTable>

我尝试了这个，只是为了测试模板，但没有任何变化:

I tried this, just to test the templating but nothing changes:

<p-dataTable [hidden]="loading" [value]="files" selectionMode="single"  sortField="Status" [sortOrder]="-1">
  <p-column field="FileName" header="Naam" sortable="true"></p-column>
  <p-column field="Status" header="Status" sortable="true">
    <template let-file="rowData">
        {{file.Status == 1 ? "Yes" : "No"}}
    </template>
  </p-column>
</p-dataTable>

请保存以得出结论，我没有正确使用它.

So save to conclude I'm not using it properly.

我们正在使用PrimeNG 1.0.0-beta.16

We're using PrimeNG 1.0.0-beta.16

推荐答案

每个p-column可以有两个模板-body和header，您应指定它是哪个.这不是强制性的，因为我认为body是默认设置，在这种情况下，这就是您所需要的，但这是一个好习惯.您还需要将pTemplate添加到模板中，以便p-column使用它，这就是p-column不会显示您提供的模板的原因.因此，您的代码应如下所示:

Each p-column can have two templates - body and header, you should specify which one it is. It's not mandatory because body is default I think and this is what you need in this case, but it's good practice. You also need to add pTemplate to template in order for p-column to use it, this is the reason p-column won't display template you provided. So, your code should look like this:

<p-dataTable [hidden]="loading" [value]="files" selectionMode="single" sortField="Status" [sortOrder]="-1">
  <p-column field="FileName" header="Naam" sortable="true"></p-column>
  <p-column field="Status" header="Status" sortable="true">
    <ng-template let-file="rowData" pTemplate type="body">
        {{file.Status == 1 ? "Yes" : "No"}}
    </ng-template>
  </p-column>
</p-dataTable>
