Angular 如何像ngFor一样在素数p-表中设置索引变量

有人能帮我吗。我想初始化索引变量，比如

*ngFor=“let d of sI.detail；let i=index”

在我的桌上

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

{{totalHeader}}
{{rowData？.totalUnits}
（{{rowData？.totalSale}}）
/{（rowData.totalUnits/rowData.totalSale）{百分比：'1.2-2'}
```

您可以在表中使用

let rowIndex=“rowIndex”

属性。这将为您提供该行的索引

<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>

{{totalHeader}}
{{rowData？.totalUnits}{{rowIndex+1}}//这里是要使用的值
（{{rowData？.totalSale}}）
/{（rowData.totalUnits/rowData.totalSale）{百分比：'1.2-2'}

希望这有帮助
