The Column button offers the following options:

This function allows you to manually add a new column to the data table. You need to provide the name, a description (optional), the type of data (one of string, number, datetime, or boolean), the position where this column is inserted in the workflow, a date/time window when the columns is visible, an optional comma-separated list of possible value (useful to restrict the values), and an optional initial value.
- Add a formula-based column
-
This function is to create a new column containing the result of the data from existing columns combined with certain basic operations such as maximum , minimum , sum , product , mean , median , etc. The way it works is by selecting the operation and a subset of existing columns to use as operands.

This function creates a new column with values randomly taken from a pre-defined collection.
