Grid display issue in IE 7

Hi i am facing a strange issue in displaying one of my grids. In IE 7 it appears collapsed but in IE 8 it looks fine. and this is only certain grid. Other grids in other pages are looking ok. I am not able to place a finger on which is causing the issue. Please find attached a screen shot and let me know the reason please.
