org-table-copy-down
org-table-copy-down is an interactive autoloaded compiled Lisp function in `org-table.el
'.
(org-table-copy-down N)
Copy a field down in the current column.
If the field at the cursor is empty, copy into it the content of
the nearest non-empty field above. With argument N, use the Nth
non-empty field. If the current field is not empty, it is copied
down to the next row, and the cursor is moved with it.
Therefore, repeating this command causes the column to be filled
row-by-row.
If the variable `org-table-copy-increment' is non-nil and the
field is an integer or a timestamp, it will be incremented while
copying. In the case of a timestamp, increment by one day.
