(data grid) is there a good workaround for obtaining other column values in FillInData for a Data Grid Table?

Now the data set is getting so large that this is too slow, looping through once to calc, then again for the grid. So we're thinking doing the calculation in FillInData would be more efficient. If possible.

I have just upload an experiment stack in the Slug's website:
http://www.aslugontheroad.co.cc/index.php?option=com_phocadownload&view=category&download=8:experiment-013-doing-sum-in-a-column-of-a-data-grid&id=7:data-grid&Itemid=63

The experiment shows how doing a sum of three columns in a column of a
data grid:
- when the dg is filling in
- when you change a value in one of the three columns.

The stack using a custom column behavior. You can access to the script
by clicking on the edit script button.
