In the future, Swing related questions should be posted in the Swing forum.
You can create a new TableModel:
DefaultTableModel model = new DefaultTableModel(2000, 52);
table.setModel( model );
I don't know if getValueAt(...) will return a null value or an empty String.
Or maybe you should be using a SparseTableModel like in this example:
