    You should define the column first before you use the comment(). Since the comment is a method from the IlluminateDatabaseSchemaColumnDefinition::class you cannot access it using the $table which is an instance of IlluminateDatabaseSchemaBlueprint::class :

    $table->string('name'); // Return type is ColumnDefinition class it means the you can access the comment() after the string(),

$table->string('name')->comment('Name of the user');

    Migration table comments for MySQL and Postgres are released with laravel version 9.14: https://laravel-news.com/laravel-9-14-0

    So, if you want to use this feature, you have to update your laravel version.
