Hi Hajime,
I verified the testcases with and without my changes on mac (v 10.7.3) webkit - r117432.
Have uploaded the results for the same.

Fmarvin%2Fbackgr_border-table-row.html

The results that I get on my machine seem to be different from the ones above. Probably am missing out on some fonts.

My fix is specifically pertaining to collapsed-borders set as "collapsed". The first table for which the image shows the difference has collapsed-borders set as "separate" and the change itself is not executed while running the testcases.
Probably the issue could be due to fonts (since the widths of blocks containing texts are shown to be different).
I also verified the renderTree dump for the block containing the diff border and found the values to be the same on both actual and expected results.

Rebaselining could perhaps fix the issue? 
Please let me know how to further proceed with this.
