How to add multiple columns in already made table in Laravel?

I want to add multiple number of columns in the already made table in Laravel . How can i add multiple columns ?  I dont know how to do add columns in my table. I can only add single column one at a time. 

Below given is my migration table up function.

  public function up()     {         Schema::create('matches', function (Blueprint $  table) {             $  table->increments('id');             $  table->string('sports');             $  table->string('match');             $  table->string('date');             $  table->string('time');             $  table->string('teamA');            $  table->longtext('teamA_flag');             $  table->string('teamB');                $  table->longtext('teamB_flag');             $  table->string('venue');             $  table->string('status');             $  table->timestamps();         });     }  This is my table whose name is matches. I want to add two columns using Laravel. The name of three columns are: email, qualification.  I am expecting to add multiple number of columns on the table (matches).
