Can any one assist me. I want to initialize index variable like *ngFor="let d of sI.detail;let i=index"

在我的 p 表中

      <tr class="text-center info">
        <td>{{ totalHeader }} </td>
        <td>

          </span>
          <span *ngIf="rowData.totalUnits && rowData.totalSale">
            /{{ (rowData.totalUnits/rowData.totalSale) | percent:'1.2-2' }}
          </span>
        </td>
      </tr>
    </ng-template>```

推荐答案

您可以在表中使用 let-rowIndex=rowIndex" 属性.这将为您提供该行的索引.

You can use let-rowIndex="rowIndex" property in your table. This will give you index of the row.

<ng-template pTemplate="body" let-rowData let-rowIndex="rowIndex">
      <tr class="text-center info">
        <td>{{ totalHeader }} </td>
        <td>
          <span>
            {{ rowData?.totalUnits }} {{rowIndex + 1}} // here is value to use
          </span>
          <span>
            ({{ rowData?.totalSale }})
          </span>
          <span *ngIf="rowData.totalUnits && rowData.totalSale">
            /{{ (rowData.totalUnits/rowData.totalSale) | percent:'1.2-2' }}
          </span>
        </td>
      </tr>
    </ng-template>
