           height:50
    }); 
    row.add(FirstNameTextField);  
    tableview.height = row.height + tableview.height;
    SearchForPatientsButton.top = tableview.height + 80;

    tableview.insertRowBefore(0,row);

    FirstNameTextField.addEventListener('click', function() {
        //DetailedPatientSearchWindow.close();

you can see tableview.insertRowBefore(3,row); and similar... i am not sure how to loop the entire thing and get the value... There are such four

tableview.setData(tableview.data);
