Im trying to search at google, but I cant find any resources to deal with this problem.. how can I delete a row together with its row header?
i dont have any problems with deleting the row, but I need to delete its header for each time I delete a row.. please I need help with this one

Don't you mean a column? If so, check out the JTable and TableColumnModel Javadoc pages.

[jhon max]

I mean the header on the west corner of the table, the header that represents each row

posted under the wrong nic this time?
why not use bigj (the one you use at java-forums)?

multiple nics, multiple posts, no wonder many don't respond to your posts,
and this one has a really simple answer
