I would suggest to continue on the path mentioned by you, i.e. starting with two columns of raw data and a third column based on calculated data offering the quick re-calculate option (yielding the update).

To illustrate, I set up a small set of molecules and randomly attributed data. To simulate data missing, I kept some of the cells empty, or used as entries the strings "0" .or. "NaN". The column to pick data from either one of the two previous columns then used the if-clause

if((vendor_1!=0), vendor_1,vendor_2)

which works reasonably well in terms of an update in the new column.

index.php?t=getfile&id=291&private=0

This however assumes the absence of a row, where both columns contain disagreeing entries ...
