Adding a summary of my comments as an answer since it appeared to have helped the OP. 🙂
As GregL points out, omitting replace: true in a directive with restrict: 'E' and <tr> as the root template node will result in invalid markup, giving rise to the incorrect rendering of the row.
However, for those using a version of Angular prior to 1.2.13 (romantic-transclusion), this solution will not be applicable due to an issue that has been noted.
A work around would be to instead to use the directive as an attribute (i.e. restrict: 'A') and appropriately modify the template such that <tr> is no longer the root template node. This will allow replace: true to be used.
