property ExportedFields: TStrings;
The ExportedFields property is used in all the TQExport4 descendant components and contains the list of the exported fields. If this list is empty (as default), then all the table fields will be exported, except BLOB ones. You can also edit the list of the exported fields by right-clicking the component and choosing "Fields editor..." from the popup menu.
