Hi Vikas,

You can define a modified version of `org-latex--org-table',
adding a new LaTeX attribute `:options'. Something like this:

#+begin_src emacs-lisp
(defun my/org-latex--org-table (table contents info)
  "Return appropriate LaTeX code for an Org table.

TABLE is the table type element to transcode.  CONTENTS is its
contents, as a string.  INFO is a plist used as a communication
channel.

This function assumes TABLE has `org' as its `:type' property and
`table' as its `:mode' attribute."
  (let* ((attr (org-export-read-attribute :attr_latex table))
         (alignment (org-latex--align-string table info))
         (opt (org-export-read-attribute :attr_latex table :options))
         (table-env (or (plist-get attr :environment)
                        (plist-get info :latex-default-table-environment)))
         (width
          (let ((w (plist-get attr :width)))
            (cond ((not w) "")
                  ((member table-env '("tabular" "longtable")) "")
                  ((member table-env '("tabu" "longtabu"))
                   (format (if (plist-get attr :spread) " spread %s "
                             " to %s ")
                           w))
                  (t (format "{%s}" w)))))
         (caption (org-latex--caption/label-string table info))
         (above? (org-latex--caption-above-p table info)))
    (cond
     ((member table-env '("longtable" "longtabu"))
      (let ((fontsize (let ((font (plist-get attr :font)))
                        (and font (concat font "\n")))))
        (concat (and fontsize (concat "{" fontsize))
                (format "\\begin{%s}%s{%s}\n" table-env width alignment)
                (and above?
                     (org-string-nw-p caption)
                     (concat caption "\\\\\n"))
                contents
                (and (not above?)
                     (org-string-nw-p caption)
                     (concat caption "\\\\\n"))
                (format "\\end{%s}" table-env)
                (and fontsize "}"))))
     (t
      (let ((output (format "\\begin{%s}%s%s{%s}\n%s\\end{%s}"
                            table-env
                            (if opt opt "")
                            width
                            alignment
                            contents
                            table-env)))
        (org-latex--decorate-table output attr caption above? info))))))

(advice-add 'org-latex--org-table :override #'my/org-latex--org-table)
#+end_src

and then:

#+ATTR_LATEX: :environment longtblr
#+ATTR_LATEX: :align <align-options>
#+ATTR_LATEX: :booktabs t
#+ATTR_LaTeX: :options [<options>]

Best regards,

Juan Manuel
