use Illuminate\Support\Facades\Schema;
 
Schema::table('users', function (Blueprint $table) {

Migration:

<?php
 
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
 
return new class extends Migration
{
    /**
     * Run the migrations.
     */
    public function up(): void
    {
        Schema::create('flights', function (Blueprint $table) {
            $table->id();
            $table->string('name');
            $table->string('airline');
            $table->timestamps();
        });
    }
 
    /**
     * Reverse the migrations.
     */
    public function down(): void
    {
        Schema::drop('flights');
    }
};

Add Column using Migration:

<?php
 
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;

return new class extends Migration
{
    /**

     */
    public function up(): void
    {
        Schema::table('flights', function (Blueprint $table) {            
            $table->string('passenger_name');            
        });
    }
 
    /**
     * Reverse the migrations.
     */
    public function down(): void
    {
        $table->dropColumn('passenger_name');
    }
};

When using the MySQL database, the after method may be used to add columns after an existing column in the schema.

<?php
 
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
 
return new class extends Migration
{
    /**
     * Run the migrations.
     */
    public function up(): void
    {
        Schema::table('flights', function (Blueprint $table) {            
            $table->string('passenger_name')->after('airline');            
        });
    }
 
    /**
     * Reverse the migrations.
     */
    public function down(): void
    {
        $table->dropColumn('passenger_name');
    }
};
