Hey everyone,

I'm trying to develop a data table, with cells that can be edited. For this table I need that a specific cell to be updated, based on other cells, therefore to be bind with other cells.

I made a basic application: https://fiddle.sencha.com/#view/editor&fiddle/2nqa

In the previous link you can find a fiddle app, where there is developed a table with months, quarters and total sum.
For the last column, total, I need to update the its value by summing up all other cells on that row. When a cell is changed, the total cell should be updated.

The question comes, how can I bind total column with values of corresponding cells?

I see that on listener I have access to editor, but not sure how can I update a specific cell.

Can some one give me some hints/support on this?
