Create Table (in the access environment)

I am a beginner and recently studied CodeWhen using the Access database to create a data table by using code, the data fields automatically numbered are not added. I have read a lot of information online, mostly about SQL Server, there are too few access databases. You can search for a post in a classic forum and view it one by one. You can use it for verification, make sure that the following method is suitable for adding an automatic number field to the ACCESS database:
Create Table data table name (ID counter constraint primarykey primary key)
Note that the second primary contains spaces. In addition, the keywords are case insensitive.
Another method I recently discovered is:
SQL = "CREATE TABLE mytb (ID autoincrement (25, 1) primary key, age INT )"
Sql2 = "create table testtb (ID autoincrement, age int, email char, primary key (ID ))"
In access, autoincrement is an automatically numbered field, and () is the initial value and step value respectively. If no value is specified, the default value is. The primary key specifies the primary key, both methods can be specified.
