How to clear contents of a jTable ?

Question

I have a jTable and it\'s got a table model defined like this:

javax.swing.table.TableModel dataModel = 
     new javax.swing.table.DefaultTableModel(data, c         


        

Answer 1

You have a couple of options:

1. Create a new DefaultTableModel(), but remember to re-attach any listeners.
2. Iterate over the model.removeRow(index) to remove.
3. Define your own model that wraps a List/Set and expose the clear method.
