Hi:
Thanks for you replying . I can implement this for the moment. According to
your code,it got position of column that i wanted to operate. if the column
fixed or the column counts doesn't  change, i can finished . but if the
column counts changed ,for example ,in my application, users get
information on the basis of theirs authorization. So sometimes it would
display 4 columns, sometimes show 3 columns.  i can set the operation
column  at last in table ,the mainly cause is  column index  has been
changed. 
could i get the last column position while the column counts changed?

Thanks & regards
