  • What table? minimal reproducible example
  • Your question is unclear. Do you want to use the same pipe for both min/max? What is value.max?
  • I need to use two pipes for max and min like this may be <tr *ngFor="let rpi of rpitable"> <td > {{rpi.north_h | MaxPipe}} </td> <tr *ngFor="let rpi of rpitable"> <td > {{rpi.north_h | MinPipe}} </td>
