doing that in the running text is asking for troubles (catcode mess)

if there is real interest in that kind of stuff we can make a module 
that does something

\starttext

\startluacode
function commands.wiki_to_table(str) -- wrong namespace
     str = string.gsub(str,"%^ *[\n\r]","\\NC\\NR\n")
     str = string.gsub(str,"%^","\\NC ")
     str = string.gsub(str,"| *[\n\r]","\\NC\\NR\n")
     str = string.gsub(str,"|","\\NC ")
     tex.sprint(tex.ctxcatcodes,"\\startTABLE")
     tex.sprint(tex.ctxcatcodes,str)
     tex.sprint(tex.ctxcatcodes,"\\stopTABLE")
end
\stopluacode

\def\startwikitable
   {\bgroup
    \obeylines
    \dostartwikitable}

\long\def\dostartwikitable#1\stopwikitable
   {\ctxlua{commands.wiki_to_table([[\detokenize{#1}]])}%
    \egroup}

\startwikitable
^ Heading 1 ^ Heading 2 ^
| Item 1    | Item 2 |
| Item 3    | Item 4 |
\stopwikitable

\startTABLE
\NC Text 1 \NC Text 2 \NC \NR
\NC Text 3 \NC Text 4 \NC \NR
\stopTABLE

\stoptext
