org-delete-backward-char
org-delete-backward-char is an interactive compiled Lisp function in `org.el
'.
(org-delete-backward-char N)
Like `delete-backward-char', insert whitespace at field end in tables.
When deleting backwards, in tables this function will insert whitespace in
front of the next "|" separator, to keep the table aligned. The table will
still be marked for re-alignment if the field did fill the entire column,
because, in this case the deletion might narrow the column.
