Spacer field type and Label control for form design, field layout problem

I have an idea on making a service request form to fill in a lot of fields for vendor creation. The following feature on form customization is highly desired:

1. Spacer field - to separate sections of fields to make the form more readable
2. Label field - static text as instruction for users to fill the form
3. Attachment mandatory + multiple (optional) - Instruct users to submit their forms with appropriate multiple attachments

Also there is a problem for <empty> field:
Consider the following design:
<Company Name> | [EMPTY]
<StaffName1> | <Title1>
<StaffName2> | <Title2>

Outcome will ignored the [empty] field and shifted field position:
<Company Name> | <Title1>
<StaffName1> | <Title2>
<StaffName2> | [EMPTY]
