[英]JavaFX Tableview sort java.sql.Date column with null at bottom on ascending order
I have a column that contains java.sql.Date and I want it to put nulls at the bottom in ascending order:我有一列包含 java.sql.Date ,我希望它按升序将空值放在底部:
Right now, they end up on top.现在,他们最终处于领先地位。
followupCol.setCellFactory((TableColumn<DisabilityCase, Date> p) ->
{
TableCell<DisabilityCase, Date> cell = new TableCell<DisabilityCase, Date>()
{
@Override
protected void updateItem(Date item, boolean empty)
{
super.updateItem(item, empty);
if (item == null || empty)
{
setText(null);
} else
{
if (!LocalDate.now().isBefore(item.toLocalDate()))
{
setTextFill(Color.RED);
} else
{
setTextFill(Color.BLACK);
}
setText(new SimpleDateFormat(DATE_FORMAT).format(item));
}
}
};
return cell;
});
Since java.sql.Date
is already Comparable
, you can use由于
java.sql.Date
已经是Comparable
,您可以使用
followupCol.setComparator(Comparator.nullsLast(Comparator.naturalOrder()));
