如何在Android studio数据库中创建多个表

Sorry to bother you all, but sometimes the help is what I have to ask for. I'm new to Android development, and currently I'm following tutorial for android database creation on youtube at channel ProgrammingKnowledge, however, it works only for one table, while I need to have 3 tables in the database, and can't get my way around it. Any help would be appreciated. Thanks in advance!Sorry to bother you all, but sometimes the help
