just wrap the code in a macro. Lua code needs a different catcode
regime and expansion rules that don’t cooperate well with the
table scanner. E.g.
\startluacode
local mathrandom = math.random
local context = context
document.get_random_number = function ()
context ("%0.1f", mathrandom (400, 600) / 10)
end
\stopluacode
\def \getrandomnumber {\ctxluacode {document.get_random_number ()}}
\starttext
\bTABLE
\bTR \bTD Distance (cm) \eTD \bTD $\Delta t$ (s) \eTD \eTR
\bTR \bTD[nr=3] \getrandomnumber \eTD \bTD t1 \eTD \eTR
\bTR \bTD t2 \eTD \eTR
\bTR \bTD t3 \eTD \eTR
\eTABLE
\stoptext
Hth,
Philipp
