to the st-sort

when sort the column, it that possible show a waiting spinner? after sorting is done, the hide the waiting spinner.

because some sort take longer time.

It's a good idea, not only for sorting but also for filtering, loading data from servers, etc...

Well, I dont know if the best approach is to create a plugin for that or if it should be in the core.

Anyway... You should post this issue in the original project (https://github.com/lorenzofox3/Smart-Table) not in the doc project.
