I find that zero references do work, albeit not quite as one might be 
led to believe by the manual.

Agreed, it does not work in James' example. And agreed, the manual 
seems to me to suggest, to the contrary, that `@1$0' should work. 
Though it does also make clear that the `$0' is superfluous and can be 
omitted, because when only the row is given, the current column is 
taken as implied. So we all agree `@1' works.

But consider the following example, which also works. Here is some 
output from fitting a linear trend in Org-Babel/R. (I've shaved off 
some decimals to fit this in an email.) Computing the TBLFM will round 
the number in each cell to three decimal places.

#+TBLFM: @2$2..@>$>=@0;%.3f

Try substituting `$0' for `@0', it works the same. @0 designates the 
current row, and the current column is taken as implied. Ditto when $0 
designates the current column. However, `@0$0' will not work.

It would seem that either one of $0 and @0 on its own in practice 
designates "the current cell".

Also, I can't think of a situation where either would be needed to 
designate a whole column or row respectively.
