Thanks for the input on this. I don't think I would ever have found that case limitation on the slot names. I am marking Solution. I still have an issue that has the Trade Size column not sorting properly, but that is another issue. Thanks again for the input.
As I looked at this further if find that the following code seems to solve the caps problem and allows for formatting in a slot template, but it breaks the sorting with up and down arrows on a least the event_date_time column ... other columns still sort , but it seems like there are multiple sorted states not just the ascending and descending I would expect. Guess I need to keep digging...
