Take a closer look at the documentation for ets:new/2

Particularly these lines (my emphasis):
The parameter Options is a list of atoms which specifies table type,
access rights, key position and if the table is named or not. If one
or more options are left out, the default values are used. This means
that not specifying any options ([]) is the same as specifying

named_table ***If*** this option is present, the name Name is
associated with the table identifier. The name can then be used
instead of the table identifier in subsequent operations.
