Property Sheets for Custom Objects
If custom property sheets have been defined for your role and for this custom object type these property sheets will be shown as tabs on the listing page
Property sheets provide a spreadsheet-like view of Custom Objects in a single table. The columns which are available in the sheet are defined for the sheet and the Role so not all attributes of the Custom Object may be shown. Some columns may also be read-only for a particular Role and Roles which have no permission to edit objects will see a read-only view of the Custom Objects.
