用

public function safeDown()
{
    $this->dropTable('{{%tableName}}');
}

删除掉，再migrate/create一个
safeUp方法如下

public function safeUp()
{
    $this->createTable('{{%tableName}}', [
        'id' => $this->primaryKey(),
        'title' => $this->string(100)->defaultValue('')->notNull()->comment('公告标题'),
        'content' => $this->text()->comment('公告内容'),
        'lang' => $this->string('20')->comment('标题语言'),
        'create_at' => $this->timestamp()->comment('创建时间'),
        'update_at' => $this->timestamp()->comment('更新时间'),
        'close_at' => $this->timestamp()->comment('结束时间'),
        ], 'CHARACTER SET utf8 COLLATE utf8_unicode_ci ENGINE=InnoDB');
    }
}
