I tried it in the Feature Browser and it is possible to drag and drop a column on the left of the fixed to near edge column.

I created a sample with this code.  I am unable to move the fixed column or to drag other columns to the left of it.  Please let me know if this works for you.

Yes, I need to enable the possibility to configure and move all other columns.

ok, but the user will still be able to drag an other column on the left of the "fixed" one.
