How can I have a field with tree input boxes instead of adding three multiple fields?

I have a customer who has requested that a field include three text boxes next to each other for a certain question where a person fills out information about the past three pay periods. He wants it to look like this: 

Any ideas on how I can do this? Any widgets that might make this happen? 

Right now I am doing a silly workaround that uses three text boxes and makes the form quite long: https://form.jotform.com/62353510286957

You can use our Fixed Format Widget for this: https://widgets.jotform.com/widget/fixed_format.

In the widget configuration, you can use underscore to define the input boxes and you can use any separator your want.
