Is this it?

  • add a column for program (Critical care only or Medicine only or both).
    • I can do that, but the table is already getting quite wide for a web page. Can we lose any of the columns we currently have? The info you mean is always visible in the pages themselves as well, in case that's sufficient. But, yes, we can tweak what the tables should show. It is done in Template:DataDictionaryQuery (details visible once you edit it...) and removing fields would be easy enough. I can show you how to add fields. Or I can add them once we confirm what we want.
      • how about adding the program as part of the sub header instead of table columns. --JMojica 13:36, 2019 June 26 (CDT)
        • I have added subheadings, or comments in headings when only one program applies. Does that work? Ttenbergen 15:32, 2019 July 4 (CDT)
