I tested with a clean emacs configuration (as proposed in orgmode page  https://orgmode.org/manual/Feedback.html#Feedback) and it worked as it should.

I am sorry for not having done that at once. I'll do it next time.

Thank you for answering my question and I apologize again for not having followed the recommendations

Best regards,

Xavier

With the table above, using <C-c C-c> on the TBLFM line, I get:

    | 1 | 1 |
    | 1 |   |
    #+TBLFM: @1$1..@2$1=@1$2

So the bug is probably fixed already in development version.
