Re: Acheiving ..2nd level grouping but withdifferentno

Hi ken
    Thanks for your time and solution .. It works great .. The reason i was trying to use KEYS was i will be later summing  and doing an
    average across rows  (not horizontally, but vertically) and i should be able to sort...
    For that reason i thought key may be convenient .. I am not sure about the PERFORMANCE though ...

thanks again for your inputs ..
 -kumar

I thought of a faster version that reuses a variable and doesn't revisit 
the source node tree for the table cells, and copied it below.  The lines 
are supposed to wrap after column 79

I hope this helps.
