ResultSet and JTable
1. ResultSet rows and columns are counted from 1 and JTable rows and columns are counted from 0
2. It is necessary to add 1 to the row or column number to manipulate the appropriate ResultSet
3. for example
moving from ResultSet column 1 = JTable column 2
If there can never be a ResultSet with column = 0 or colum = 1, then what would be the first column number in a JTable. Help me understand. Thanks.

Re: ResultSet and JTable
Since JTable starts from zero, and ResultSet starts from 1 (which is your point 1), then your point 3 is clearly wrong, as:
ResultSet 1 = JTable 0
