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 is myTable  you can do following    DefaultTableModel model   new DefaultTableModel    myTable setModel model

Basically  it depends on the TableModel that you are using for your JTable  If you are using the DefaultTableModel then you can do it in two ways   DefaultTableModel dm    DefaultTableModel table getModel    dm getDataVector   removeAllElements    dm fireTableDataChanged       notifies the JTable that the model has changed   or  DefaultTableModel dm    DefaultTableModel table getModel    while dm getRowCount    gt  0        dm removeRow 0       See the JavaDoc of DefaultTableModel for more details

This is the fastest and easiest way that I have found   while  tableModel getRowCount   gt 0                           tableModel removeRow 0                 This clears the table lickety split and leaves it ready for new data

You must remove the data from the TableModel used for the table    If using the DefaultTableModel  just set the row count to zero  This will delete the rows and fire the TableModelEvent to update the GUI     JTable table      DefaultTableModel model    DefaultTableModel  table getModel    model setRowCount 0    If you are using other TableModel  please check the documentation
