Edit table row inline on click of edit in Angular

I have a table where data is populating. Each row has an edit link. I want to edit only a particular row on click of edit link. Right now its’ showing edit option for all the rows.

Also I want to show the text in a input box on click of edit.

Here is my code.

<tr *ngFor="let row of backendData.report"  class="hover-highlight">

          <td class="benchmark_name">
             {{row.name}}
          </td>
          <td>
            {{row.value}}
          </td>
          <td>
            {{row.description}}
          </td>
          <td>
              <button *ngIf="enableEdit" (click)="enableEdit=false" class="btn page-secondary-action-btn" ng-click="cancel()">Cancel</button>
              <button *ngIf="enableEdit" id="saveBtn" class="btn page-primary-action-btn" (click)="saveSegment()" type="submit">Save</button>
              <a class="table-row-action edit-action" *ngIf="!enableEdit" (click)="enableEdit = true">
          <i class="fa fa-pencil" uib-tooltip="Edit" tooltip-trigger="mouseenter" tooltip-append-to-body="true" tooltip-placement="left"></i>
        </a>
          </td>
          <td>

          </td>
        </tr>

My current output looks like this
