I tried to use the LaTeX radio tables that I included in a file that I

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?
