Ui_table custom validator

General
1

Hello Forum

I want to add a custom validator to my ui_table. (Tabulator)
The validator should only allow numbers smaller than the next number. I wrote this function for that:

function(cell){
   if (parseInt(cell.getRow().getData().temp) >= parseInt(cell.getRow().getNextRow().getData().temp)){
       return false;
   }   else {
       return true;
   }
}

I don't know why this function doesn't work. I can write any number and its every time true. Can somebody help me?

Here is my example flow.

Did you already tested the function in Tabulator without nodered?
