Controlling multiple columns sort order in GWT 2.2 CellTable

Hi,

At this point, I figured out how to create a multiple column sort. I
create 1 ListHandler and hadd that to the CellTable with the
addColumnSortHandler method. I set each column I want to be sorted
with setSortable(true) and then set multiple Comparators for each of
those columns using the ListHandler.setComparator method.

At the very end, I do this:
cellTable.getColumnSortList().push(column3);
cellTable.getColumnSortList().push(column2);
cellTable.getColumnSortList().push(column1);

This way column1 becomes the primary column to sort by, following by
sorting on column2, and then column3.

The question is this... How is the column sorting order affected when
I click on column2, for example? Obviously, if I do that, column2
becomes the primary sort column, but what is the secondary? column1?

What if I want to make it that when the user clicks on column2, the
column sorting order should be column2, column3, column1? How do I
accomplish that at the same time keeping a regular column sorting
order when the user click on column1 (i.e., column1, column2,
column3)?

Any help would be much appreciated!

Thanks,
Yaakov.
