Sparklines not Centered in Cell

[LabraLime]

I have sparklines inserted into the cells to show progress WoW, the sparklines at the top of my table are not centered like the ones for the rows I have no data for.

Ideally I'd like for all of the sparklines to be centered vertically and horizontally inside the cells. Any tips on how I can center the lines inside the cell?
