Making a JTable Non Editable

There are times when you want to display a JTable in your Swing app, but do not want to the user to be able to edit the cells. Here's a simple way to accomplish this task via the DefaultTableModel:

  DefaultTableModel model = new DefaultTableModel(6,7){
   
 public boolean isCellEditable(int row, int column)
 {
     return false;
 }
  };

In the example above, I'm creating a DefaultTableModel model that has 6 rows and 7 columns. I'm overriding the isCellEditable() method, the method used by other methods and classes to know whether or not a JTable cell can be edited, and returning a boolean value of false in all cases. I could have also returned false for only selected rows and columns by adding conditional logic .
