I am creating a report with an overview about my rails in an ongoing order. My Rails are adressed with numbers cause i am using explo. I now that other systems also use Letter Number Combination for Adressing. I think that is the reason why this column is a string column which sorting behavior ist like a string. But it didnt work for sorting numbers and create a report from it which shows me the right numerous order. Of course i am able to work around it with using an extra column which is number based but hope that you find a way in the future to optimize the behavior of rail column sorting.
