1. Define the number of columns in DefaultTableModel. Add a data row to the
end of DefaultTableModel's data vector with [fewer] columns than previously
defined. Try to read one of the columns that DefaultTableModel has added
automatically to ensure the correct number of columns.

Vector data = new Vector();

// Add a row with just one column,
// DefaultTableModel.newRowsAdded() should add a second column with
value null

data.addElement( row0 );

Vector row1 = new Vector();

System.out.println( "Read contents of cell (0,0)" );
System.out.println( tm.getValueAt( 0, 0 ) );

System.out.println( "Read contents of cell (0,1)" );
// This call succeeds and prints "null"
System.out.println( tm.getValueAt( 0, 1 ) );

System.out.println( "Read contents of cell (1,1)" );
// This call fails with an ArrayIndexOutOfBoundsException
System.out.println( tm.getValueAt( 1, 1 ) );
