If I switch on change tracking before inserting  a column in a tabular, 
there is no way to know what column is new.

Should the tabular itself be marked as changed in this case ? I see that 
at least I should marked is a changed when one of its cells is changed.

Also, is there a reason why your change status does not have a author 
and time associated with it?
