Hello,

On this page https://orgmode.org/manual/Advanced-features.html
it says
- '!' :: The fields in this line define names for the columns, so that
  you may refer to a column as '$Tot' instead of '$6'.

However, when I experimented with this I found that the first of the
following two tables works (i.e. the empty cells are filled in
correctly), but the second doesn't (the only difference is the
replacement of $4 with $c3 in the second table):

|---+----+----+----|
| ! | c1 | c2 | c3 |
| # |  1 |  2 |    |
| # |  3 |  4 |    |
|---+----+----+----|
#+TBLFM: $4 = $c1 + $c2

|---+----+----+----|
| ! | c1 | c2 | c3 |
| # |  1 |  2 |    |
| # |  3 |  4 |    |
|---+----+----+----|
#+TBLFM: $c3 = $c1 + $c2

Is this a bug?

Thanks,

Paul

It seems to me it's a bug in the documentation.

Currently, column names are not allowed in the LHS (Left Hand Side) of
the formula ('org-table-get-stored-formulas' assumes it).  Although I'm
not sure why.

In other words, you'll need to use the real column number
for the column that holds the results. This should work:

   | ! | c1 | c2 | c3 |
   |---+----+----+----|
   | # |  1 |  4 |  3 |
   | # |  3 | 10 |  7 |
   #+TBLFM: $3 = $c1 + $c2

 However, the following, with the column name on the RHS, works

|---+----+----+----|
|   |  3 |  4 |    |
| ^ | c1 | c2 | c3 |
|---+----+----+----|
#+TBLFM: $c3 = $c1 + $c2

Could allowing column names on the LHS in my first example be put on a todo
list?

By the way, there is a small error in your example as your $3 should be $4.

Thanks,

Paul

 It seems to be on a todo list already as the following exists:

Oops. Sorry. Thanks for reporting it.

Right. Thanks for the link!

You just need to wait a little :-)

You should probably send an email to the emacs bug:

   bug#66213: named columns in org tables ()

that it may be closed.

In the earlier section https://orgmode.org/manual/Column-formulas.html,
we do explain this caveat:

"The left-hand side of a column formula can not be the name of column,
it must be the numeric column reference or ‘$>’."

Thus, I see no reason to amend the manual. (And I hope that we will
remove this restriction after
https://list.orgmode.org/877cqwbpa2.fsf@runbox.com is merged)
