Null's not null?

Putting Null into one or more slots in a Table and printing the Table 
shows "Null" (without quotes) at the corresponding positions, as also 
does ToString[Null].  I don't think that's what the Help message says:

      "Null is a symbol used to indicate the absence of an 
       expression or a result. When it appears as an output 
       expression, no output is printed."

I can use a string with a couple of empty spaces ("__") to represent an 
occupied but not empty slot in a Table, but that just looks clumsy to 
me.  Is there a truly non-printing Null symbol?
