Displaying Data for Different Sub-Types

Displaying Data for Different Sub-Types

The display options above make it possible to display entries requiring different numbers of rows, and for row/column fields to have different contents and data types - or even to be absent.

The example above has been modified so that:

• Both _LOCAL and _ID options are displayed
• The top entry (green) row has been given notional values
• The second existing joint (blue row 2) has been given the _ID suffix and an explicit label and title

This presents several display problems:

• The _ID row ( JID and TITLE ) row is undefined for existing joints #1 and #3
• The _LOCAL row ( RAID and LST ) is undefined for all existing joints.

It can be seen from the figure above that this problem is solved by simply "greying out" the data fields that are not relevant.
