CellTable isn't a complete replacement of PagingScrollTable, but we put a
lot of work into the API to make it more clear and extensible. We'd like to
create a full featured enterprise CellTable, but we also have a lot of other
projects going on and don't have the dev time to do it right now.
in IE8 I see 3-4 seconds 100% CPU just to let the browser calculate
mouse over row highlighting, when showing a lot of rows.
Have you tried looking at it with SpeedTracer? We tested with large tables
(100 rows), and the hover code is pretty straight forward. In past
applications, we've seen performance problems when hovering due
to descendent style selectors because of the way they are implemented in
browser.
For example, you have this CSS style defined:
.myRandomWidget td {
padding: 3px;
}
And you have a CellTable that is NOT myRandomWidget, then changing the hover
style of the row will cause IE to walk up from every TD in the CellTable
trying to match the style definition. In the degenerate case, where
CellTable is not myRandomWidget, this means walking up to the body element.
This is a native browser implementation, and the only solution is to avoid
descendent style selectors.
Thanks,
