Hide unused token fields

Hi, 

I've tried to find a solution for this before posting, but couldn't find an appropriate solution. 

What I'm trying to do is to essentially create a list in an email that's driven by an excel sheet.  

For example, in each email, there's 6 token fields that needs to be populated with info. However, not all token fields will be used for all versions of the email. It can go from 1-6. My question is, is it possible to hide the fields that are not populated with info, so the spacing of the email will look correct. 

1. <Parameters 1>, <Parameters 1a>
2. <Parameters 2>, <Parameters 2a>
3. <Parameters 3>, <Parameters 3a>
4. <Parameters 4>, <Parameters 4a>
5. <Parameters 5>, <Parameters 5a>
6. <Parameters 6>, <Parameters 6a>
