Greetings Tada Community-
I recently encountered an issue where I had a grouped table with the first column in the table being the “grouping” field. I also had a Summary row at the bottom to show totals of different columns.
When grouped by the first column, the Summary title “Sum” (or whatever title you chose) did not show.
When I moved the grouped column to any other column in the table the Summary title DID show.
So, if you are grouping a table AND have a summary row make sure the grouped column is any column EXCEPT the first column.
Hope this helps,
