hi, i have plenty of rows' record, which generated from user keyin data after user click on "add" button, and using ArrayList and HttpServletRequest

my doubt is , after the table record display , how to i delete certain row of record ? and also, if the records first column with the unique sequence number indication, when second record deleted , how the following number match back ? means initial third record with sequence number "3" now become "2" instead due to second record deleted ...

should i hv checkbox or just delete button beside of every single row for deletion, which one is better idea in sense of easier maintenance and coding

anyone mind to guide me on this ? thank you very much for guiding
