Deleting a table or a column in phpMyAdmin not using Laravel's options

What will happen with my Laravel project if I will manually delete a table or a column in phpMyAdmin? I know the ways how to do that using Laravel's Schema, but it feels for me that deleting a column or a table using phpMyAdmin is a much quicker and easier way.

I tried to google it but couldn't find any information about this.
