I use different screens in my layouts, but the general format is the same, with only one or two cells changing. Because the cells that change have different elements, they render with different sizes, which changes the sizes for the surrounding cells.
So I'm trying to set some of the cells to have fixed height and width. And if I do this for one or two cells, it's ok. But if I do it for "too many", I wind up seeing white space, instead of the specified background color (blue or green).
Am I doing something wrong?
