sortRows() not using custom sort algorithm

In the docs, it says “by default the sorting type is taken from the column’s setting” but if that sorting type is a custom one, it doesn’t seem to use it.
Seems a bit inconsistent. Is there something I’m missing?

Found the solution in your code. You’re using “str” as default sorting for grouped data instead of whatever column sorting method is set.
Would be nice if you would patch that. I’ll send you detailed info via email/ticket or something.

Thank you for your note. It will be observed.
