Laravel:如何创建从表中删除多个列的迁移文件?

When I drop a column, I use following command to create migration file,

php artisan make:migration drop_institue_id_column_from_providers

And migration file:

public function up()
{
    Schema::table('providers', function(Blueprint $table) {
          $table->dropColumn('institue_id');
    });
}


public function down()
{
    Schema::table('providers', function (Blueprint $table)
    {
        $table->integer('institue_id')->unsigned(); 
    });
}

If I want to drop multiple columns, I can write migration file this way,

public function up()
{
    Schema::table('providers', function(Blueprint $table) {
          $table->dropColumn('institue_id');
          $table->dropColumn('institue_name');
          $table->dropColumn('institue_address');
    });
}


public function down()
{
    Schema::table('providers', function (Blueprint $table)
    {
        $table->integer('institue_id')->unsigned(); 
        $table->char('institue_name');
        $table->char('institue_address');
    });
}

But What is the command to create that migration file? Thank you.

    I assume this is just a question about naming convention for the migration class.

    If so then it does not matter what the file\class is called, as long as it gives you a good idea of what it does.

    So it could be something like:

    php artisan make:migration drop_institue_columns_from_providers
