Improvement: No of rows when integrating e.g. ind. metrics

[jdpo]

After clicking "proceed" when integrating individual (possibly also grouped) metrics, the summary from shiny does not gives detailed statistics but not the number of rows integrated. Would be very helpful here, I guess, since it is difficult to make sense of the number of rows from the long format, especially if for e.g. some ind length, age, weight are provided but for others only length...

@jdpo I think you are wrong: the skim indicates the number of groups (not metric)

the dt show the table in wide format

and one validated, the indicated number of rows correspond to the number of groups and then metrics
