No, the list to which you refer includes the listing "blank table entries to be filled in," because there are Nemeth-specific rules for some instances of such things.
To answer your broader question:
If a table is done in UEB, then 2016 Formats, which BANA has approved and which will be released soon, says to use a series of dot 5s for blank cells within a table (and explain the use of these in a transcriber's note).
If a table is transcribed in Nemeth Code:
1) If there is an actual blank space, you would use the general omission symbol.
2) If there is a dash or a shape indicating something to be filled in, use that dash or shape as Nemeth requires.

If you would like to discuss this further, please include an example of the print table(s).
