CellTable updating individual/non-consecutive rows

[Rike255]

I can't figure out a good way to update a single row of data after
using setRowData() to populate a CellTable.

Specifically, I have an ArrayList of objects that represent rows that
need to be updated, but they are not consecutive. Is there a way to
update one (or multiple non-consecutive) rows in a celltable without
refreshing the whole thing (or from an index to the end)?

Thanks!

If I understand you, when you create the CellTable you can add a setFieldUpdater. With this way you have control to update the rows like you want (you have a "int index").

http://google-web-toolkit.googlecode.com/svn/javadoc/2.1/com/google/gwt/user/cellview/client/CellTable.html

See you.

You'll call setRowData(int,List) for each set of consecutive rows to update:

table.setRowData(2, Collections.singletonList(thirdRow));

table.setRowData(10, Arrays.asList(eleventhRow, twelfthRow));

Thanks guys both answers look like they'll help, I'll read into both.

Also, rendering the whole table is generally really fast. I would test it out to see if it is worth the effort to selectively update rows.

Well, actually, I'm not even sure Cell widgets currently re-renders only selected rows. It might very well render the whole thing whatever you do, selective rendering coming in a future release as a performance enhancement.

There are hooks in HasDataPresenter for rendering a specific subset of rows,but I haven't actually tested it.
