is an option for Cell which gives the label to use for a particular cell.


  • CellLabel->"" specifies that no label should be used for a cell.
  • Cell labels are displayed when the setting ShowCellLabel->True is made. They may also be displayed in modified form with the setting ShowCellLabel->Automatic.
  • Cell labels are typically generated automatically when cells appear as input or output to the Wolfram Language kernel.
  • Cell labels are automatically deleted when a cell is modified or saved if CellLabelAutoDelete->True. If CellLabelAutoDelete->Automatic, then they are only automatically deleted if the cell is modified.
