# 2 Adds columns to a Data Table based on a document property. 
# The doc prop is a comma separated list of columns for the data table to show.
# use a multiline doc prop control to create a csv list of cols

# 2.3 Parse columns from selection and add to tablePlotVisual
for property in selection:
   for col in property.split(","): tablePlotVisual.TableColumns.Add(cols[str(col)])
