Let us discuss in details below. Fill the first list with text from your CSV file, Set parsing regular expression (note that default regular expression works on a row with two columns separated by comma), Set index of key column (this column will be used for join), Repeat the same for the second list (note that default regular expression for the second list works on a row with two columns separated by space), Set join type: inner join, left outer join, or right outer join, Set column separator for the resulting list. It is easier to understand this notion when the base is an integer, for example, 2 or 3: In the case of the natural logarithm, this is somewhat less intuitive because its base, e, is not an integer.
