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 (in that 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?
