Details

- CellLabelTemplate is not used if ShowCellLabelTrue or CellLabelAutoDeleteAutomatic is set.
- CellLabelTemplate-><||> uses the default cell labels provided by the kernel.
- CellLabelTemplate-><|"In"template1,"Out"template2|> specifies a StringTemplate to use for input and output labels, respectively.
- CellLabelTemplate takes an association with the following elements:
-
"In" None string template to use for input labels "InExpired" "In[]:=" string template to use for labels of inputs that no longer correspond to a running kernel "Out" None string template to use for output labels "OutExpired" "Out[]=" string template to use for labels of outputs that no longer correspond to a running kernel - The templatei are typically specified as a raw string that is interpreted as StringTemplate with two positional arguments. `1` represents the position line number and `2` represents a form qualifier, if present, such as //InputForm.
