The next test was to determine whether table groups like TBODY could receive the same treatment. In this case, the answer was a no. With the TR positioned relatively, you could get a background image on the TBODY to display in each TR but it tiled like the default behaviour between TR and TD. In other words, the problem managed to shift up.
Unfortunately, no amount of relative positioning seemed to unlock this mystery. In fact, setting a relative position on the TBODY made the background disappear altogether.
Thankfully, IE8's rendering engine has been written from scratch and the current beta does not exhibit this behaviour.
Feel free to check out the test page I put together, which demonstrates the alpha PNG over the background set in the table row.f2富二代官网入口
