[O] manipulating org-tables as matrices - operations on org-table in diagonal direction for columns and rows

[Daniel Kiertscher]

Hello,
org-tables already support very helpful operations for manipulating the 
order of rows and columns. But we could implement some operations based 
on the concept of matrices, making org-tables even more usefull for 
drafting ideas using matrix layouts.
Maybe you are interested in the operations I am suggesting and can help 
me to implement them.
Maybe you have some questions or suggestions, improving or generalising 
this approach?
Here are the first sketches of a part of the functions on org-table 
which I am missing for quite a while now.
I am not very familiar with development in elisp though.

;; move field  in org-table in diagonal direction
(defun org-table-move-field-upleft ()
  "Move Point one line up and one char left."
  (interactive)
  (org-table-move-row-up)
  (org-table-move-column-left))
(global-set-key (kbd "C-<f5>") 'org-table-move-field-upleft)

(defun org-table-move-field-downright ()
  "Move Point one line up and one char left."
  (interactive)
  (org-table-move-row-down)
  (org-table-move-column-right))
(global-set-key (kbd "C-<f8>") 'org-table-move-field-downright)

(defun org-table-insert-field-with-row-and-column-upleft ()
  "Insert a field with row and column at the uper left corner of the 
field at point."
  (interactive)
  (org-table-insert-column)
  (org-table-insert-row))
(global-set-key (kbd "C-<f9>") 
'org-table-insert-field-with-row-and-column-upleft)

(defun org-table-duplicate-field-with-row-and-column-upleft ()
  "Duplicate a field with row and column at the uper left corner of the 
field at point."
  (interactive)
  (org-table-insert-column)
  (org-table-insert-row))
(global-set-key (kbd "C-<f10>") 
'org-table-duplicate-field-with-row-and-column-upleft)

(defun org-table-delete-field-with-row-and-column ()
  "Delete a field with row and column."
  (interactive)
  (org-table-delete-column)
  (org-table-kill-row))
(global-set-key (kbd "C-<f11>") 'org-table-delete-field-with-row-and-column)

;; move point in org-table in diagonal direction
;; The functions org-table-move-point-.. are note working yet.
(defun org-table-move-point-upleft ()

  (previous-line)
  (org-table-previous-field)) ;how to stop if in a corner?
(global-set-key (kbd "C-<f6>") 'org-table-move-point-upleft)

(defun org-table-move-point-downright ()
  "Move Point one line up and one char left."
