           Summary: Massive slow down with large CSS tables
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh Intel
               URL: http://downloads.syncbyte.com/table_test.html
        OS/Version: Mac OS X 10.6
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: CSS
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: r.trost at syncbyte.com


Large HTML tables with CSS styles massively slowing down the browser. I've created a test-case with 15.000 rows for better comparison. 
While Firefox and Opera stay very responsive, all WebKit based browsers become extremely  sluggish and slow. 

Within a Web-App that makes heavy use of  JavaScript, this becomes an issue with much smaller tables already.  In the test-case, I've removed all other page elements, JavaScripts and other CSS styles, because it would almost stall the browser if I've left them in.

This problem only shows up with CSS tables.
