I fail to see which column you mean.

#TH perhaps? I think, that can be calculated under linux by

(a) counting the directories in /proc/22429/task using readdir
or
(b) get the nlink of /proc/22429/task and subtract 2, which should give
the same as (a), and, better than (a), should also be atomic

I have implemented the child_count script, in this way. I was
wondering what is more convenient.

This one, is good. I did not think about this approach.
