[O] Bug: Is "radio tables" broken?

[Charles Millar]

I tried to use the LaTeX radio tables that I included in a file that I 
set up a year ago.

When point was in the first cell of the table, C-c C-c gave

C-c C-c can do nothing useful at this location.

I copied the LaTeX radio table (section A.6.2) from the manual into a 
scratch.org file, put the point in the first cell, C-c C-c 'd with the 
same result.

Out of curiosity I changed one of the "Days" number for January, C-c 
C-c'd the TBLFM: and again the same message.

Is there a bug or what am I missing in the manual?
