LibreOffice Base: Why are there different icons next to my tables?

LibreOffice Base has flawlessly connects to my ODBC connections. The only thing I am wondering; why some of my tables have a table icon, which the others have an icon that looks like two tables sitting on top of another?

Hi

The Views have a different icon (and are listed with tables). You can refer to Base_Handbook to get information on Views.

Thanks for the link. I never knew such handbooks ever existed.
