st: automatic disclosure in tables

["percy" <percy.scheller@gmx.de>]

Hello dear colleagues, 

I once discovered an ado, which helps to automatically disclosure/suppress
cell content if it makes a reidentification of single persons possible.
Unfortunatelly this is years ago, I can't remember it or find it in my
ado-files. Has anybody a hint for me?!

Thanks in advance

Example (see low educated male, infact you might need to suppress a second
information, too):


. table sex edu
----------------------------------
          |       Education       
      Sex |    low  medium    high
----------+-----------------------
     male |      1       6       4
   female |      8      53      26
----------------------------------
