I have a JTABLE and I am adding data to him, how can I do so that he can fence me with the data and if I get to remove something from the table that comes back and count the rows of the table, but in a column he will fence me showing the amounts of records entered.
axis:
item/ Nombre/ costo
1 / p1 / 100
2 / p2 / 50
3 / p8 / 60
