I'm not sure I understand that eXcell types "coro" and "co"

I’m not sure I
understand that eXcell types “coro” and “co” – do they
correspond to the HTML element “” and
“”, respectively. Could you please give me an example
for “coro”?


“coro” - simple selectbox 
(without multiple property )


“co” - select
box with ability to add some other value ( combobox ) ( you can replace
“coro” with “co” in any of default grid samples to check
difference) <o:p></o:p>
