            $table->increments('id');
            $table->string('title');
            $table->text('content');

class AddIntroColumnToArticles extends Migration

    public function up()

    }

    /**

        Schema::table('articles', function (Blueprint $table) {
            $table->dropColumn('intro');
        });
    }
}

再次运行migrate命令,进行修改

php artisan migrate
如果需要运行$table->dropColumn('intro');还需要导入一个包运行composer require doctrine/dbal

migrate回滚命令

php artisan migrate:rollback

laravel tinker

php artisan tinker
