Here is my bash script and do `C-c l` (org-table-copy-region) on
first table and `C-c ;` (org-table-paste-rectangle) on second table.
(~/dev/tmp/taks-file.tex have first tak's mention contents.)

```sh
make clean
./autogen.sh
./configure --prefix=$HOME/.local/head
make -j6
./src/emacs -Q ~/dev/tmp/taks-file.tex --eval "             \
  (progn                                                    \
    (setq truncate-lines t)                                 \
    (setq debug-on-error t)                                 \
    (require 'org)                                          \
    (require 'org-table)                                    \
    (orgtbl-mode)                                           \
    (global-set-key (kbd \"C-c l\")                         \
       (lambda ()                                           \
         (interactive)                                      \
         (org-table-copy-region (1+ (org-table-begin)) (- (org-table-end) 2)))) \
    (global-set-key (kbd \"C-c ;\")                         \

         (set-buffer-modified-p nil))))"                    \
2>/dev/null
```
