I Bold my lines between groups using the Previous() function. If the Previous value of the group by field is different then set BoarderWidth = 1.5 else BoarderWidth = 1.
So in the BoarderWidth Top Expression for each cell I want bolded I put...
=IIF(Previous(Fields!GroupID.Value) <> Fields!GroupID.Value ,"1.5pt","1pt")
In this example GroupID is the field the data is grouped on. The same method can be used for color.
Hope this helps.
