Straight table, show a visual on change of company or a group

[dwighttrumbower]

Is there a way in a straight table to visually show when a group changes? In the following example, the last company 1 row would have an underline on the whole row. 

company 1  

company 1  

company 1  

company 1  

company 2

company 2

Thanks

If(FieldName <> Above(FieldName) AND Not IsNull(Above(FieldName)), perhaps? The second part is to avoid highlighting the top row.

I thought this was the solution and it possibly could be. I just have no idea where to put it?
