Lock a column

Is there a way to lock a column via js or xml or both?

What do you mean by “lock” column?

If you want to lock column position - you can use split mode

If you want to lock edit operations for column, it can be done with next code
       if (ind==SOME)
          return false;
       return true;
where SOME - index of column in question.
