i need to filter the rows according to file name, then calculate the size difference between the previous file and the most current, and add that value to the datatable before i write it to XML

How can i do calculations on previous rows liike:

jul 24 2002    100    +100%
jul 23 2002    50    0%

so the current file, is 100% bigger than previous file.

thanks
