Adding an otherwise row
You can add an otherwise row to a condition column for when none of the other conditions
in the column are correct.
Procedure
To add an otherwise row:
Right-click the condition cell and click
Otherwise.
A new, partially completed row is added below the row you right-clicked. The cell below the condition cell you selected contains the text otherwise.

The otherwise row runs when the conditions next to the otherwise statement are true, but none of the cases in the same group as the otherwise cell are true.
Results
In a condition column, you can automatically create and complete rows for all the values from an enumerated domain.
