Adding leading zero's can also be done.
But it works very well and is SIMPLE as asked.

The "Bubble sort" sort is well known to me.
Used it already 20 years back in assembly. 
May be for the user who did ask for a way to do it.

I hope this wil be implemented by QT, it must be done by the nearest part of 
the widget/control on the screen,  else re-sort before and re-fill is may be 
the only good way.

In MS ListView it can be done from C and VB with a API call for text,nummeric 
and date types and is supported by the comctr32.dll.
The file Explorer does it and is quick, less 2 second to fill and sort for 
5000 items (avg 2000/sec). Konqueror has already problems to build the list 
with the content of /usr/bin, 5 seconds for only 1300 items (avg 260/sec).
Doing this in gambas interpreted source swapping 5 columns and 1000 rows?
Your pleasure.
