Plate reader data analysis

I am trying to analyses plate reader result, but I find that difficult
to do calculation for each single data on the table. It always row or
column calculation. Is there a way to do calculation for each single
cell in the table?

I did not really get your question. What did you already try? Which nodes did you use? Which calculation do you want to use per cell? Why is it alway row or column calculation?

Can you explain a bit more in detail?
