Creating sum of numbers from table widgets in Label widget?

Hello everyone, help me how to accomplish the task:
Screenshot example below

It is necessary to sum the numbers in the “Summa” column and write the result in the Label (“Sum1”) field

@jamessigur Add the below JS code in the Text property of the Label widget

(function() {
   let sum = 0;
   Table1.tableData.forEach(element => {
   sum += element.Summa;
   return sum;
