i need help on clearing tables guys
i want to clear the tables then get all the elements from JDBC again just like what it does on form load the problem is when i clear it which i did. but whenever i call the upTable it loads 6 columns instead of just three

this method is triggered by a button
also please comment on the way i put rows is it proper to use a constructor object or a different way is way much better?
