试试这个：
(defun my-build-tab-stop-list (width)
(let ((num-tab-stops (/ 80 width))
(counter 1)
(ls nil))
(while (<= counter num-tab-stops)
(setq ls (cons (* width counter) ls))
(setq counter (1+ counter)))
(nreverse ls)))
(add-hook 'c-mode-common-hook
#'(lambda ()
;; You an remove this, if you don't want fixed tab-stop-widths
(set (make-local-variable 'tab-stop-list)
(my-build-tab-stop-list tab-width))
(setq c-basic-offset tab-width)
(c-set-offset 'defun-block-intro tab-width)
(c-set-offset 'arglist-intro tab-width)
(c-set-offset 'arglist-close 0)
(c-set-offset 'defun-close 0)
(setq abbrev-mode nil)))
