\definecolor[fondpaille][c=0,m=0,y=0.2,k=0]

\startuseMPgraphic {tablebackground}
  fill OverlayBox withcolor \MPcolor{fondpaille} ;
\stopuseMPgraphic

\defineoverlay

  [\ifnum\currentxtablerow=1
       \useMPgraphic{tablebackground}%
   \else\ifnum\currentxtablecolumn=1
       \useMPgraphic{tablebackground}%
   \fi\fi]

\setupxtable[background=tablebackground]

\starttext
\startluacode
local letters_1 = { "A", "B", "C", "D", "E", "F", "G", "H", "I", "J" }
local letters_2 = { "A", "0", "1", "1", "0", "", "", "", "", "" }
context.startxtable({"align={middle,lohi}, width=1.25cm,offset=0.8ex"})

context.startxrow()
context.startxcell({"background=color,backgroundcolor=white,frame=off"})

context.stopxrow()

context.startxrow()
