- Custom column allows user definition of creating columns by using formula.
- Conditional column allows user a column based on if else conditions.
3. Using Custom Column. (click on Custom Column, the below dialog box opens)

Enter column name, write formula using the fields required for calculation which are seen on the right of screen, and click on ok.
The new column is created as below.

4. Using Conditional Column. (click on Conditional Column option, the below dialog box opens )

Enter column name, and write the conditions based on which column values are to be created (The values can be string or numeric or a field value ) and click on Ok.
