[WIP] Takes care of some issues Alexander had experienced, part 1
@astigsen 

Changes the appearance of table indices to gray, small and right aligned

Always shows floats and doubles with exactly three decimals

Reloads after cancelling editing to return to three decimals.

Also fixes a mouse over issue (mouse pointer should always change over links)
Sure, just haven't gotten around to cleaning this method up yet.
