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?
