Hi, Mirko build in SWT.Virtual a while ago for Grid. He also did some benchmarking against the TableViewer. I’m not sure if he blogged about it. However, I don’t think the RAP team adopted the virtual/lazy capabilities.
In addition to Grid we also have XViewer. I’m not sure if this runs in RAP but you can take a look at that viewer as well.

And it provides a lot of additional features out of the box, e.g. filter row, groupby, print, export, summary row etc. For a better overview of the features you should step through the examples application. To be honest, I am not very familiar with Nebula Grid and therefore can't tell anything about the feature set there. I just used it once for performance comparison. Using it is similar to the JFace viewer. NatTable has a completely different approach in the architecture, and is therefore more difficult to get started with. Not sure about your use cases and requirements, but compared to the effort for making NatTable RAP ready, I would go for some other table widget and see if it provides what I need.

Can you help for a comparison? As for the NatTable, I made a try and imported org.eclipse.nebula.widgets.nattable.core into a RAP 3.0.2 workspace: most of the problems pointed out by Angelo in 2012 are still there. I commented out the parts with errors and was able to see something somehow [Inline image 1] but it is totally unusable this way. Probably going through each commented part with attention may be a way. But must admit that GridViewer, with all the JFace viewer powerful concepts, raises the doubt about going on in this direction. I don't want to put the two projects one against the other: just would like to understand them better.

It is 5 years old, so I think (and hope) the issues with missing API is gone with a more current version of RAP. Also the hint to use Require-Bundle instead of Import-Package is something I will probably never add to one of the projects I'm responsible for. ;-) On Mon, Feb 6, 2017 at 9:31 PM, Wim Jongman <[email protected]<mailto:[email protected]>> wrote: Thanks Dirk, I re-read that thread and Angelo’s answers looks very useful. http://markmail.org/message/7fcad6ofm3vbex5p#query:+page:1+mid:oypkofpqvfnfsfuv+state:results Cheers, Wim From: [email protected]<mailto:[email protected]> [mailto:[email protected]<mailto:[email protected]>] On Behalf Of Dirk Fauth Sent: maandag 6 februari 2017 21:12 To: Nebula Dev Subject: Re: [nebula-dev] NetTable & RAP To be honest, I can't remember anymore. But probably reading the configuration on rendering constantly. As I am not familiar with RAP, therefore I can't tell anything. And it was years ago when I was last contacted on that topic by someone from the RAP team. There was a discussion about 5 years ago, without any further conclusion: http://markmail.org/message/7fcad6ofm3vbex5p Also there are some posts by the RAP team saying that NatTable is not supported as it doesn't fit: http://eclipsesource.com/blogs/2014/10/15/rap-3-0-m2-whats-new-in-widgets/ https://www.eclipse.org/rap/noteworthy/3.0/ I even heard that they added support for KTable, so actually I'm not sure what the real blocker is. But that is my state of information. On Mon, Feb 6, 2017 at 8:58 PM, Wim Jongman <[email protected]<mailto:[email protected]>> wrote: What architecture would that be?

The RAP team once said that the architecture does not match. I never made any attempts to make it work, nor did the RAP team look closer afaik.
