Answer

Your code is actually working correctly. You are not seeing the rowspan working because the absolute positioning that is used for the sticky header. I updated your JS Fiddle with a few tweeks so you can see what is going on. http://jsfiddle.net/x62v5ea8/2/

You can see in the HTML I commented out the cell that will used by the rowspan and added a .test class with a height and background color so you can see that the cell is now fully expanding. Alternatively you can remove the position: absolute and you see the same results but your header wont be sticky anymore.
