I have two separate datagrids, they both use the same class as the custom headerRenderer. I am having problems thinking of a way to sync the size of each headerRenderer. If grid1 has two rows worth of text (word wrapping is enabled) and grid2 has one rows worth of text. I want both grid1 and grid2 to both be the height of two rows worth of text. I am basically trying to synchronize the only line that is of variable height in these grids.
