Making JTable cells uneditable

Question

I am trying to make all the cells of a JTable uneditable when double clicked by the user. I have read a lot of forum posts and the general consensus is to create a new table

Answer 1

This line creates a new JTable and implicitly creates a DefaultTableModel behind the scenes, one that holds all the correct data needed for the JTable:

storesTable = new JTable(tableData, COL_NAMES);

And this line effectively removes the table model created implicitly above, the one that holds all of the table's data and replaces it with a table model that holds no data whatsoever:

storesTable.setModel(new MyTableModel());

You need to give your MyTableModel class a constructor and in that constructor call the super constructor and pass in the data that you're currently passing to the table in its constructor.

e.g.,

public class MyTableModel extends DefaultTableModel {

   public MyTableModel(Object[][] tableData, Object[] colNames) {
      super(tableData, colNames);
   }

   public boolean isCellEditable(int row, int column) {
      return false;
   }
}

Then you can use it like so:

MyTableModel model = new MyTableModel(tableData, COL_NAMES);
storesTable = new JTable(model);
