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

I think you meant that you want to clear all the cells in the jTable and make it just like a new blank jTable. For an example, if your table contains 40 raws, you can do following.

DefaultTableModel model = (DefaultTableModel)this.jTable.getModel();
model.setRowCount(0);
model.setRowCount(40);
