I recently found from @JordanCClark’s post that you can use getColumnAsList to get column data from a table as a list 
From him:
# Get column names. Coerce it to a list to use the same names in the new dataset.
headers = list(dataIn.getColumnNames())
# Get tag paths as a list
tagList = dataIn.getColumnAsList(headers.index('InterlockedTags'))
