Is it possible to invoke the auto row sorter in a jtable

Question

is there anyway to invoke the auto row sorter in a jtable that is created by using

setAutoCreateRowSorter(true);

i'm trying to get it to sort by a default column without the user having to click on on the column header.

Answer 2

TableRowSorter rowSorter = (TableRowSorter) table.getRowSorter();
List<SortKey> keys = new ArrayList<SortKey>();
SortKey sortKey = new SortKey(2, SortOrder.ASCENDING);//column index 2
keys.add(sortKey);
rowSorter.setSortKeys(keys);
rowSorter.sort();

curious: setSortKeys is documented to trigger a sort (if the given list is different than the current), no explicit sort() needed - or have you found corner cases where it was? – Amphistylar

I haven't had problems before. I just didn't read the API correctly and always added the sort :( – Lamoree

I think you have to use setSortsOnUpdates(true) method from TableRowSorter class.

that's not an answer to the question as I understand it, could be me mis-understanding, though :-) – Amphistylar
