5.20.1. Adding columns¶
The Column button offers the following options:
- Add a new column
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.
- Add a column with random values
This function creates a new column with values randomly taken from a pre-defined collection.
