You can add a checkbox field and put the numbers as the option. There are 16 options so in the Spread Columns options, put 16. 

Then you can inject a custom CSS codes to align them.

Example Form: https://form.jotform.com/60154409449962

The injected CSS:

#id_1 .form-multiple-column .form-checkbox-item {

width: 20px;

}

#id_1 is the field ID of the checkbox field (https://www.jotform.com/help/146-How-to-find-Field-IDs-Names).
