Printing a header with tabulated-list-mode

Printing a header with tabulated-list-mode

[Heime]

I want to print an alist with a header using tabulated-list-print

(setq foo '((a . ["a1" "a2"]) (b . ["bb1" "bb2"]) (c . ["ccc1" "ccc2"])))
(tlprint-alist foo)

But the header is not being displayed.

(defun tlprint-alist (alist &optional outbufr keytl valtl)
  "Print an associated list via `tabulated-list-print'."

  (let*
      ( (bufr (or outbufr (get-buffer-create "*Alist*")))
        (keytl (or keytl "Key Title"))
        (valtl (or valtl "Value Title")) )

    (with-current-buffer bufr
      (tabulated-list-mode)
      (setq tabulated-list-format
             (vector (list keytl 20 t) (list valtl 20 t)))
      (setq tabulated-list-sort-key (cons keytl nil))
      (setq tabulated-list-entries
            (mapcar (lambda (pair)
                      (list (car pair) (cdr pair)))
                    alist))
      (tabulated-list-init-header)
      (tabulated-list-print) )))

This is my main function using tabulated-list-mode, if you can get anything from it:

(defun rcd-db-report (title entries format database-type db-handle table sort-key 
			    &optional refresh highlight-list place id return-function)
  "RCD database report.

TITLE is buffer name."
  (setq rcd-db-current-database-type database-type)
  (let* ((buffer (generate-new-buffer-name (rcd-notes-name title))))
    (let* ((buffer (get-buffer-create buffer))
	   (mode-map (rcd-db-table-mode-map table)))
      (cond ((string-equal table "edit") (switch-to-buffer buffer))
	    (rcd-dont-switch-windows (switch-to-buffer buffer))
	    (t (switch-to-buffer-other-window buffer)))
      (setq tabulated-list-format format)
      (setq tabulated-list-entries entries)
      (setq rcd-db-edited-table table)
      (setq rcd-db-current-database-type database-type)
      (setq rcd-tabulated-refresh-function refresh)
      (setq rcd-current-return-function return-function)
      (rcd-db-list-mode)
      (use-local-map mode-map)
      (setq rcd-tabulated-marked-items nil)
      (setq rcd-db-current-database-handle db-handle)
      (setq rcd-db-current-table (or (alist-get "table" place nil nil 'equal) table))
      (setq rcd-db-current-table-id id)
      (setq tabulated-list-padding 1)
      (tabulated-list-init-header))
    (setq tabulated-list-sort-key sort-key)
    (tabulated-list-print t)
    (when highlight-list
      (rcd-highlight-list highlight-list))))

I see the header line displayed.
