How to just update a table and add new line with Laravel?

I am migration table as below;

 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();
        });
    }

I want to do as below;

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();
        });
    }

how can I update the new line(gsm line) without refreshing(php artisan migrate:refresh)
