[O] recalculate tables

[Michael Welle]

Hello,

in a table like the following C-u M-x org-table-recalculate fills the
third column as expected:

|---+---+----|
| 3 | 4 |    |
#+TBLFM: $3=$2-$1


But if the table finishes with a line, that doesn't work anymore:

|---+---+----|
| 3 | 4 |    |
|---+---+----|
#+TBLFM: $3=$2-$1


Then if I change the table to the following, recalculation works again:

|   |   |    |
|---+---+----|
| 3 | 4 |    |
|---+---+----|
#+TBLFM: $3=$2-$1

Is that intended behaviour?
