Answer 1

Try this code..

DefaultTableModel dm = (DefaultTableModel)table.getModel();
dm.getDataVector().removeAllElements();

Answer 2

The exception you are seeing is coming from the Swing Thread (AWT-EventQueue-0). The exception is happening because the JTable is drawing itself (on the Swing Thread) at the same time that you are modifying the DefaultTableModel on some other thread.

Do not do that! All changes to the table model must happen on the Swing Thread.

See Last word in Swing Threads

Use EventQueue.invokeLater(new Runnable() {...}); or something similar.

This is my method:

DefaultTableModel model=(DefaultTableModel)table.getModel();
            int rc= model.getRowCount();
            for(int i = 0;i<rc;i++){
                model.removeRow(0);
            }

I use this code

dtm_vendor = new DefaultTableModel();
jTable_vendor.setModel(dtm_vendor);
