Filter rows from a table view
I am displaying a list of data in a TableView. Now I want to apply a filter
to only allow certain data from within that list to be displayed on the
TableView, without actually removing those entries from the list.
I have to imagine there is an easy way to do this? Is there filter class
that I can set to the tableview? I tried the DisabledRowFilter, but looks
like that just disables the row and doesn't actually remove it from the
view.
Thanks!

There used to be a FilteredList class, but it was dropped (for 2.0 I think, or maybe earlier). We dropped it because it was conducive to memory leaks but also because this type of functionality is fairly easy to implement in app code.

Thanks greg!
Is there a possibly to add in the future a way to apply a filter class that
would just simply determine whether that row gets painted? Or is that not
the design?

You have to actually remove the data from the list. Otherwise, TableView wouldn't be able to efficiently map row indexes to item indexes in the backing list (for painting, hit detection, etc.).
Easiest way to do this is to create a copy of your source list that represents the filtered contents. That way you can easily revert to the source list if the user clears the filter.
