you can try
,----[ C-h f org-table-map-tables RET ]
| org-table-map-tables is a compiled Lisp function in
| ‘../org-mode/lisp/org.el’.
|
| (org-table-map-tables FUNCTION &optional QUIETLY)
|
| Apply FUNCTION to the start of all tables in the buffer.
|
| [back]
`----
to go to all tables in the buffer, then inside FUNCTION you would need
to check first if the table is named and is the one your are looking
for. If so, get the table as list, work on the list, and insert the new
table replacing the old one (org-dp-create-table inserts a table when
given a nested list).
Finally move point to the end of the inserted table, so the mapping
function can continue.
PS
org-element and org-dp allow you to do these things too, maybe even
more comfortably if you are familiar with these libraries. But right now
I'm not really able to give you a working example in reasonable time.
