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?
