I don't have an example but I can explain you one way of doing it.

• Use a "TableView"

• Each column should be a "TableColumn". This "TableColumn" should be related to an "ObsverbableList" with :

  YourColumn.setCellValueFactory(
          cellData ->CellData.getValue().yourObservableList.yourFloatProperty());
  

• The numbers inside your list should be "FloatProperty".

• Set a listener on all of them except the last one. (You can do this in a loop)
  • Each listener should call your sum function. This function should calculate the last element of your list = the sum of the other element in the list
  • The "TableView" will automatically update it self.
