        $table->increments('id')->unsigned()->comment ('主 Key');
        $table->text('content')->comment ('內容');
  
        $table->integer('article_id')->unsigned ();
        $table->foreign('article_id')->references('id')->on('articles');
        $table->timestamps();
        });
    }
    public function down()
