Setting detailed column names

Column names in the table header are set automatically. They are element property names. You cannot change column names. If an element has some properties with the same name (for example, in associations or if a tag of stereotypes is selected as a column), detailed column names could provide more precise information.


To see detailed column names


  • On the Options toolbar, click  and then select Show Detailed Column Name.
    The group name (between brackets) to which the selected property belongs, and/or the stereotype name (just before the property name), will be displayed in the column heading.

The following diagram shows three different columns with the same name for the association element: NameName (Role of A), and Name (Role of B) and a column for the class element with the stereotype «Teacher». Name (Tags). If the command Show Detailed Column Name were not selected, there would be four columns with the same headings, i.e., Name.
