It seems spaces aren't allowed for table name. see http://opengrok.libreoffice.org/xref/core/sw/source/ui/app/app.src#657 "The name of the table must not contain spaces" You can have this message if you insert a table then select it, property and try to validate a new name which includes a space. Now why it wouldn't be allowed, I don't know.
Actually spaces are not allowed => set to enhancement Renamed to "Allow spaces in table name"
Since it is an useful enhancement I changed the status to NEW.
