Erasing whole JTable

Question

do you know the best way to erase whole JT ?

Answer 1

It depends on your model. If you can access it, modify its content, else :

yourJTable.setModel(new DefaultTableModel());

Answer 2

Don't do it like HEBERT suggested, you break the link between your data object and your table model. Bad MVC design.

Ideally, you have access to the data model. Assuming it's a List in the variable myDataList

myDataList.clear();
myTable.getModel().fireTableDataChanged();
