php-如何仅更新表并使用Laravel添加新行？

在数据库表中如下所示；

 public function up()
    {
        Schema::create('current_adresses', function (Blueprint $table) {
            $table->engine = 'InnoDB';
            $table->increments('id');
            $table->string('current_name',50)->nullable();
            $table->string('current_surname',50)->nullable();
            $table->string('telephone',25)->nullable();
          $table->timestamps();
        });
    }

我想做如下

public function up()
    {
        Schema::create('current_adresses', function (Blueprint $table) {
            $table->engine = 'InnoDB';
            $table->increments('id');
            $table->string('current_name',50)->nullable();
            $table->string('current_surname',50)->nullable();
            $table->string('gsm',25)->nullable();
            $table->string('telephone',25)->nullable();
          $table->timestamps();
        });
    }

我如何不刷新即可更新新列(gsm列)(php artisan migration：refresh)

解决方法:

添加新的迁移-

public function up()
{
    Schema::table('current_adresses', function($table) {
        $table->string('gsm',25)->nullable();
    });
}

public function down()
{
    Schema::table('current_adresses', function($table) {
        $table->dropColumn('gsm');
   });
}
