How to pass table into a function at Lua?

Hi all,

I try to crate a table with {aa="bb", cc="aa"} and as parameter.

local table = {aa="bb", cc="aa}
luci.util.copcall(my_print, table)

function my_print(table)
   print(table["aa"])
end

At my_print, I always get table is nil. How do I fix this? Please advise. Thanks.
