请问如何对表能实现按前面的数字直接排序(后跟有表)

!lstt1
((51054.9 ("污水" "PE" "300" "" "直埋" 0.33))
(51053.3 ("路灯" "PVC" "500X100" "" "管道" 0.0))
(51035.9 ("供电" "砖" "1500X1800" "" "沟道" 0.0))
(51057.3 ("路灯" "PVC" "50" "" "管道" 0.0))) Command: (setq lstt1 (vl-sort lstt1 '<))
; error: bad argument type for compare:
(51053.3 ("路灯" "PVC" "500X100" "" "管道" 0.0))
(51054.9 ("污水" "PE" "300" "" "直埋" 0.33))
请问用什么函数对lstt1表能实现按前面的数字直接排序？(在线等)

(setq lstt1'((51054.9 ("污水" "PE" "300" "" "直埋" 0.33))
(51053.3 ("路灯" "PVC" "500X100" "" "管道" 0.0))
(51035.9 ("供电" "砖" "1500X1800" "" "沟道" 0.0))
(51057.3 ("路灯" "PVC" "50" "" "管道" 0.0)))) (setq lstt1 (vl-sort lstt1 (function (lambda (e1 e2)
(< (car e1) (car e2)) ) ))) 哎，帮助里说得很清楚。。。一查便知！
