Are there any decent GWT Timeline libraries out there?

Example

I basically need something close to the following image: Timeline example

Existing Libraries

I already tried GWT Planning, but I couldn't get it working. Right now I'm looking into GWT Simile Timeline.

Implementation

If there aren't any other usable timeline libraries, do you have any ideas how I might implement one myself?

Is using a table a good idea?

Won't there be some performance issues? (due to the fact that GWT already uses a lot of tables for the layouts and it takes some time until the browser renders the page).

EDIT

Final decision

I reviewed GWT Simile Timeline, but it doesn't do what I want and besides that the documentation is not finished and it seems to me that the project is discontinued. I'll follow Daniel Kurka's suggestion (using cellTable).

Open to suggestions

If there are any other suggestions I'm open to them...

ANOTHER EDIT

Is it better if I use FlexTable for this type of things? I saw that it allows me to use any type of widget (but I think it has performance issues). I want to have up to 100-150 widgets on the timeline. Will performance be affected by this number of widgets?

Implementing a timeline with the Grid Widget would bring a lot of performance issues ( since a grid consists of widgets, which bring some overhead)

You might want to take a look into cellTable to see how bulkrendering is done.

Basically it renders the html as a string an sets it with SetInnerHTML. Event Handling is only done once on the root element. If you want to your own timeline this is a good starting point.
