InstanceRowWidget and InstanceTableWidget
InstanceRowWidget is an optional widget for slots of type Instance with single cardinality (at most equal to 1). It shows all slot values for the instance. (The default widget, InstanceFieldWidget, only shows the name of the instance that is selected as the value of the slot.)
InstanceTableWidget is very similar to InstanceRowWidget, except that it is available for Instance slots with multiple cardinality (at most not specified or greater than 1). So, it can display multiple rows of information.
For information on how to customize the display of this widget, see Customizing an InstanceRow- or InstanceTableWidget.
