### Overview
On Android, trying to remove the separator lines between cells in a TableView with a custom renderer does not work. In the custom renderer, the line

> Control.DividerHeight = 0;

does not affect the separator line in the TableView.

### Steps to Reproduce
1. Run the attached Android project

### Expected Results
There are no separator lines between the items.

### Actual Results
The lines are still rendered even though DividerHeight is set to 0.

Craig mentioned in another report that this used to work before Forms 1.3: https://bugzilla.xamarin.com/show_bug.cgi?id=26656#c3

Bug #26104 is also similar to this, but they are using a custom cell renderer instead to remove the line from the section header only.
Comment 2 Mihail 2015-12-12 08:01:34 UTC
I am also able to reproduce the bug.
Comment 3 adamhewitt 2016-04-19 18:29:19 UTC
I'm also seeing this in 2.1. Looking at the decompiled TableViewModelRenderer, the GetView function adds a divider to the returned item rather than leveraging the divider/dividerHeight API of the Android ListView. Perhaps most importantly, it sets the background resource of the divider to a hard-coded value that the consumer (me) can't override.
Comment 4 Mike Rowley 2016-09-09 15:03:11 UTC
I am seeing this in as well.

Xamarin any update or work around on this?
Comment 5 Mike Rowley 2016-09-10 17:34:57 UTC
Anyone else that is in need of a work around, its not ideal but the custom render code is in this forums post.

Comment 6 adrianknight89 2016-11-02 22:13:59 UTC
See https://github.com/xamarin/Xamarin.Forms/pull/500
Comment 7 Samantha Houts [MSFT] 2016-11-15 20:14:35 UTC
TableView is short term looking to be replaced by ListView which will grow to support all the features and niceties that TableView provides.
Comment 8 adrianknight89 2016-11-15 20:26:35 UTC
@Samantha, can you guys maybe create an FAQ on the repository homepage to communicate this kind of plans (it would help with anyone submitting or fixing bugs)? I think we need one. We also need a roadmap.
