GWT CellTable with frozen header and start column

I need to freeze the first column and the first row of data in CellTable so that users can scroll through the data, but still see the labels on the “axes”. The first column should scroll when the user scrolls up and down, and the title bar should scroll when the user scrolls left and right. Think "Stop Lists" in Excel.

I am using GWT 2.1 and am ready to write my own widget to do this if solutions no longer exist. My question consists of two partners:

  • Do any widgets already have this behavior?
  • Any suggestions if I am going to implement this myself?

Thanks!

I have implemented the solution myself. Check out http://larkolicio.us/ScrollTable/ExperimentTables.html

This is a LayoutPanel with three Absolute Panels inside it. The frozen columns are CellTable, the main part is CellTable, and the heading is Grid - I could not find a way to set the width of the CellTable column! ScrollHandler connects the main part with two frozen parts. There is a bit of delay - I would appreciate it if someone could find a way to get rid of the lag between sections.

I earned to use it, and stopped. This is not a universal widget. Please feel free to use it at your own risk.

This implementation is pretty good. I just tested it. However, it needs some changes to support asynchronous loading. GWT Issue 188 , covering a similar request for improvement, was created in October 2006 ?!

Thanks for sharing.
