Adding and removing columns

To add or remove columns

1. To open the available columns list:
   
   • On the table toolbar, click the Columns to open the menu with common properties corresponding to element types that have been selected for the table.
   • On the table toolbar, click Columns > Select Columns to open the dialog with all properties, including tags of stereotypes corresponding to selected element types.

    Using the Select Columns dialog, you can choose to display the properties of the specified element type, as well as the properties that are subtypes of the specified element type.

   The Select Columns command is not supported in the Glossary table.

2. Do one of the following:

  • Unselect the properties you do not want to see as columns in the table.

Adding and removing custom columns

To add custom columns

2. In the Expression dialog, specify criteria for the custom column, and click OK.

   Additional information

    - You can read more about it in Specifying criteria for querying model, as the procedure for custom columns and for derived properties is the same.

    - You can also select to show implied relationships in the table. The procedure for specifying which relationships to display in the table is the same as described in Specifying dependency criterion.

To remove custom columns

1. Right-click the custom column header you want to remove.
2. From the shortcut menu, select the Remove Custom Column command.
   

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: Name, Name (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.
