So I have 2 cells within a row and selected stretch on the row cell alignment Each has content of different size, a background color and a border but the 2 columns do not match in height. http://cleaning.paston2.webfactional.com/cellstretch/ If I select cell alignment top, center or bottom it works but stretch does not. Please advise.
