Multiple TDs in a TR, but on separate lines?

I have run into an interesting problem. I can ONLY modify CSS, not HTML, on an app I'm using. The app generates 4 cells per row, but I want only 1 cell per row. If I set the width of the TD to 90%, it seems to work, putting each TD on it's own "line."

It works, that is, in Chrome, Safari and Firefox browsers. IE seems to try to force the row/cell model. Is there any way I can accomplish this? It's tough to find an answer in a search engine. :/

THANKS!
