I have some data that I want to add to existing columns and Honestly I have no idea how to do it.

Thing looks somewhat like this

I have no issues with getting the data, but I can’t figure out how to append data without creating new columns and to append data related to column only in destinated column (let’s say, that column 3 is only for temperature that I get from sensor and I don’t want it to be written in “COL2”)

I searched over the stack overflow and other forums, but there’s nothing about my task
