Contact Label Migration Rollback

Hi, everyone. I'm doing this and that because I'm practicing migration, I'm asking you because there's something I don't understand because I'm trying to create a todos table and add a column with the artisan make: command.

Below are the steps you actually worked on.

// column additional migration file
class AddColumnTodosTable extends Migration
{
    public function up()
    {
        Schema::table('todos', function (Blueprint $table) {
            $table->string('title');
        });
    }

    public function down()
    {
        Schema::table('todos', function (Blueprint $table) {
            $table->drop('title');
        });
    }
}

We confirmed that additional column migration will be rolled back by rolling back, but the todos table disappeared. I don't know the cause, but was the down method written incorrectly? Below is a captured image of the above. I ask for your help me. <
