HI:

In my thesie, I need add a caption to table or figure with
\bicaption{中文标题}{English title}

I can't find the easy way to do this in org-mode ,so  I add :caption  to
#+attr_latex:

for example:

#+attr_latex:  :caption \bicaption{...}{....}


But the below function doesn't work as expected, someone can help me?
thanks!

#+begin_src emacs-lisp
(defun org-latex--caption/label-string (element info)
  "Return caption and label LaTeX string for ELEMENT.

INFO is a plist holding contextual information.  If there's no
caption nor label, return the empty string.

For non-floats, see `org-latex--wrap-label'."
  (let* ((label (org-element-property :name element))
     (label-str (if (not (org-string-nw-p label)) ""
              (format "\\label{%s}"
                  (org-export-solidify-link-text label))))
     (main (org-export-get-caption element))
     (short (org-export-get-caption element t))
     (caption-from-latex-attr (plist-get (org-export-read-attribute
:attr_latex element) :caption)))
    (cond
     ((and (not main) (equal label-str "")) (format "%s"
caption-from-latex-attr))
     ((not main) (concat label-str "\n" (format "%s"
caption-from-latex-attr)))
     ;; Option caption format with short name.
     (short (format "\\caption[%s]{%s%s}\n"
            (org-export-data short info)
            label-str
            (org-export-data main info)))
     ;; Standard caption format.
     (t (format "\\caption{%s%s}\n" label-str (org-export-data main
info))))))
