Define macro as wrapper for parameters of a command
I'm trying to define a macro that is a little wrapper to a common parameter of a command. The macro is expanded, but the parameter is not taken into account by the command.
The macro, sp is used inside an extreme table. Below are code and result: note that sp is expanded, but the parameter is not used. How can I define that macro to expand to an usable parameter?
% define macro sp
definesp{[bottomframe=off]}
% table setup
setupxtable[frame=off, bottomframe=on]
starttext
startxtable
startxtablehead
startxrow
startxcell Head 1 stopxcell
startxcell Head 2 stopxcell
stopxrow
stopxtablehead
startxtablebody
startxrow
startxcell A1 stopxcell
startxcell sp A2 stopxcell
stopxrow
startxrow
startxcell B1 stopxcell
startxcell stopxcell

As to explain why I reached at this: I'm writing documents in Markdown, and using Pandoc to generate PDF through a conversion to ConTeXt. Pandoc doesn't allow column or row spans on tables, so I'm figuring out how to fake that using borders. Turning bottom border off for a cell would make it seems as spanned. And using a macro for this is necessary in order to use default alignment of Pandoc tables.

When a command takes a optional argument ConTeXt always checks if the next character after the command is [ which isn’t the case in your example.
To pass the argument which is hidden in the sp command to startxcell you have make the sp command expandable which can be done with defineexpandable. The next step is to expand the content of sp which can be done with expanded.
defineexpandablesp{[bottomframe=off]}
starttext
startxtable
startxrow
startxcell Cell 1 stopxcell
expanded{startxcell sp Cell 2 stopxcell}
stopxrow
stopxtable
stoptext
The better solution to pass the same arguments to a xtable multiple times is to create a named setup and pass the name as argument to the startxcell command.
setupxtable [sp] [bottomframe=off]
starttext
startxtable
startxrow
startxcell Cell 1 stopxcell
startxcell [sp] Cell 2 stopxcell

Imho there is no definition of sp that will do it. You would need a variant of startxcell that expands the following command once:
