如何在 prime ng table 中单击时获取 tr 的第一个 td 值

Question

如何在点击时获取 tr 的第一个 td 值 condition.If 我点击第一个 td 我想获取 angular 中的值 7.Please 不要为 tr 编写任何内联代码.我们只需要通过像 find table inside 这样的编码来使用。我们如何通过 viedchild 或元素引用使用 p-table id="dt" 来做到这一点？

演示：https://stackblitz.com/edit/p-table-primeng-v6-t1k6ng?file=src/app/app.component.html

app.component.ts:

@ViewChild('dt') public dataTable: DataTable;

app.component.html:

<p-table id="dt" [columns]="cols" [value]="cars" [scrollable]="true" [rows]="10"  [virtualRowHeight]="30" [loading]="loading"
    [virtualScroll]="true" (onLazyLoad)="loadCarsLazy($event)" [lazy]="true" [totalRecords]="totalRecords">

    <ng-template pTemplate="header" let-columns>
        <tr>
            <th *ngFor="let col of cols">
                {{col.header}} 
            </th>
        </tr>
    </ng-template>
    <ng-template pTemplate="body" let-rowData let-columns="columns">
        <tr style="height:30px">
            <td *ngFor="let col of cols">
                {{rowData[col.field]}}
            </td>
        </tr>
    </ng-template>
</p-table>

注意：请不要这样写内联代码：通过打字稿或 javascript.

<ng-container *ngFor="let col of cols; let i = index;">
  <td (click)="handleClick(i)">
     {{rowData[col.field]}} 
  </td>
</ng-container>

primeng table已经有选择功能，只需要设置选择模式和属性绑定选中的item

<p-table selectionMode="single" [(selection)]="selectedCar">
....
</p-table>

<ng-template pTemplate="header" let-columns>
    <tr>
        <th *ngFor="let col of cols">
            {{col.header}} 
        </th>
    </tr>
</ng-template>
<ng-template pTemplate="body" let-rowData let-columns="columns">
    <tr style="height:30px" [pSelectableRow]="rowData">
        <td *ngFor="let col of cols">
            {{rowData[col.field]}}
        </td>
    </tr>
</ng-template>

this how you set the selected item on clikc and will be boound to the selected property that has defined by [(selection)]='...' not this [pSelectableRow]="rowData" will set the holde item as selected but you can set the selected item to just the first colume data of the tr like this [pSelectableRow]="rowData['vin']"
