I have data that can be bound to a control. However, depending on types of records, I need to change how DIFFERENT fields (<td>tag) are displayed. For example, I have accounts and if the AccountType field is Total its number field should underlined and children of subheadings must be indented. I also need to allow user to change # of columns (time periods). I was using render blocks but this needs to be a re-usable control.
