You can define dependencies between two columns for control elements of the Input table type. The reaction of the second column depends on what a user enters or enables in the first column.
Model an input table and add all required columns.
Activate the Column dependencies tab.
Click Add to define a dependency. To remove a dependency, click Remove.
In the Source column column, enter the name of the column that is to influence the behavior of another column.
Note that you must define all behaviors. For example, if the check box in the first column is enabled, you also have to specify the behavior if the check box in the first column is not enabled.
In the Trigger column, enter the condition that must be met to trigger the defined behavior. What is offered in the Trigger column depends on the element type selected in the column.
In the Target column column, specify the name of the column whose display depends on the first column.
In the Action column, define what the second column is to display depending on the triggering column.
Click Save.
You have defined a dependency between two columns. You can remove a dependency by clicking the relevant row and then Remove.
