Hi,
On Edward Tufte's website, there is a discussion on zebra coloring in tables[1]. One of the suggestion is to add a horizontal rule after every third line or shade three lines with one background color and the remaining three with another background color.
Is there an easy way to do this with natural TABLEs? I can do something like:
\setupTABLE[row][1,2,3][background=color, backgroundcolor=gray]
\setupTABLE[row][7,8,9][background=color, backgroundcolor=gray]
but it requires knowing the number of lines in advance.

Natural tables have “odd” and “even” keywords for \setupTABLE but none in the way you like it. What I would do is to use a overlay in combination with metapost to create the background but there is no global register to access the current column/row of a cell, e.g. \currenttablecolumn (this name is already used by tables) and \currenttablerow.
I've added 4 status macros:

\starttext

\bTABLE
     \bTR
         \bTD 
(\currentTABLErow,\currentTABLEcolumn,\nofTABLErows,\nofTABLEcolumns) \eTD
         \bTD 
(\currentTABLErow,\currentTABLEcolumn,\nofTABLErows,\nofTABLEcolumns) \eTD
         \bTD 
(\currentTABLErow,\currentTABLEcolumn,\nofTABLErows,\nofTABLEcolumns) \eTD
         \bTD 
(\currentTABLErow,\currentTABLEcolumn,\nofTABLErows,\nofTABLEcolumns) \eTD
     \eTR
     \bTR
         \bTD 
(\currentTABLErow,\currentTABLEcolumn,\nofTABLErows,\nofTABLEcolumns) \eTD
         \bTD 
(\currentTABLErow,\currentTABLEcolumn,\nofTABLErows,\nofTABLEcolumns) \eTD
         \bTD 
(\currentTABLErow,\currentTABLEcolumn,\nofTABLErows,\nofTABLEcolumns) \eTD
         \bTD 
(\currentTABLErow,\currentTABLEcolumn,\nofTABLErows,\nofTABLEcolumns) \eTD
     \eTR
\eTABLE

\stoptext
