Let me elaborate with *one* example: Consider that a column in a 
table contains a calculuation, and that the result of adding the 
content of the cell on row 2 and 3 is presented as aresult in the 
cell row 4, and that the cell in row 4 is also used as header for 
the cell in row 5. Then the content in row 4 should be presented 
with a TD and not a TH, even if it also acts as a header for the 
subsequent cells.
