You can set a new model using the JTable.setModel() method

Check the Javadocs for details

Damn - I was using the inline javadoc in the eclipse editor and I missed it, but I went back and checked and it's there. – opike May 30 '11 at 16:45
Very helpful in the case of a JXTreeTable as well, where you might have to use `setTreeTableModel()`. – Stéphane Bruckert Apr 09 '15 at 09:35

When you change the model you are stuck with old column titles. getColumnName() only gets called on initialization.

Al morce

so it is not possible to change the column names as well? In my case, I want to make a data viewer table, it gets initialized without data and filled once a different thread provides the model. But, as you said, column names are not appearing! – A. Harkous Jul 13 '18 at 08:29
