Could mean they are set as 'hidden' tables. There is also a toggle in Navigation Pane settings to show 'hidden' tables. Hidden tables will show as 'greyed out'.

Oke Thanks... Why do you want to hide a table?
Access hides system tables by default. Those can also be set as viewable and will be greyed out.
Some developers will hide tables not being dealt with at present during db development.
