I'm less enthused than you are about your solution... the markup doesn't really capture the relationship of the tags to the rows/cols -- you wouldn't purpose something like that for laying out table headings would you? As you say, it has the advantage of working in MathML+CSS environments, but unfortunately, IE+MathPlayer is not one of them -- it only is "close" in that environment. I strongly encourage filing bugs and pushing on implementors to fix those bugs rather than resorting to "contortions" to get things to work. Stretching chars and spanning rows/cols are important for several notations, so it is not some obscure feature that needs to be implemented. My two cents...
