This depends on the TableModel you are using. What is your table model?

Good, that's easy. Any kind of Object will work. You can either convert to an Integer object, which preserves the numeric quality if you plan any further calcs, or convert to a String object, which displays with the minimum overhead.

new Integer(sum);
String.valueOf(sum)

that's very good idea, but would be impossible in case that JTable has used RowSorter or RowFilter

1/ if isn't there implemented and used RowSorter or RowFilter, add TableModelListener,

2/ move TableHeader (then you lost) from Top to the JTable's bottom and if isn't there implemented and used RowSorter or RowFilter, add TableModelListener,

add(table, BorderLayout.CENTER);
add(header, BorderLayout.SOUTH);

3/ if is there implemented and used RowSorter or RowFilter dirty hack
