Example
A table for a model of the EPC type contains, for example, green highlighting for functions because functions are displayed in green in the model. In a table for a BPMN diagram, a task appears in blue, as in the diagram.
A flashing cursor in an empty row indicates that entries can be made.
A gray background indicates that no entries can be specified.
In BPMN diagrams, lanes are outlined by a thicker line.
