如何使用Proc SQL生成Proc Tabulate格式的统计表格？

我正在尝试确认是否可以使用Proc SQL生成下方的Proc Tabulate表格。

TITLE;
TITLE1 "Enrollment by Plan, Region, and Dual-Benefit Status";

PROC TABULATE
DATA=WORK.

;

VAR rcpnt_ssk;
CLASS pmp_plan /    ORDER=UNFORMATTED MISSING;
CLASS capt_region_cd_desc / ORDER=UNFORMATTED MISSING;
CLASS opt / ORDER=UNFORMATTED MISSING;
where elig_month = &elig_month2;
TABLE 
    capt_region_cd_desc 
    all = 'Total'  ,
    pmp_plan *opt *(rcpnt_ssk=' ' * N=' ' )
    all = 'Total'  *(rcpnt_ssk=' ' * N=' ' )        ;
;

RUN;

RUN; QUIT;
TITLE; 

我已查阅相关参考资料，但仍存在困惑。
