You can create table cell with StringConverter, that will convert your object to cell presentation. You can realize own StringConverter for your class

cell.setCellFactory(TextFieldTableCell.forTableColumn(new StringConverter() {

        @Override
        public String toString(AnyClass object) {
            return null;
        }

        @Override
        public AnyClass fromString(String string) {
            return null;
        }
    }));

Also JavaFX contains some default converters. E.g. IntegerStringConverter for your case,

TextFieldTableCell.forTableColumn(new IntegerStringConverter())
