I asked for help, how to order that each time I add an item then the item number in column
1 move to column 2, column 2 moves to the column 3, column 3 to 4 and so on.
product | 1 | 2 | 3 | 4 | total
------------------------------------------
pro - 1 | 2 | 1 | 0 | 0 | 3
so the next execution (2)
product | 1 | 2 | 3 | 4 | total
------------------------------------------
pro - 1 | 4 | 2 | 1 | 0 | 7
so the next execution (3)
product | 1 | 2 | 3 | 4 | total
------------------------------------------
pro - 1 | 2 | 4 | 2 | 1 | 9
Therefore, please help and thanks
