运行下面的code产生表格
ods listing close;
ods rtf file = "D:\from desk\example_lines.rtf" style=journal;
proc report data=lines NOWINDOWS
     STYLE(report)=[frame=box rules=cols]
     style(header)={borderbottomwidth=2pt borderbottomcolor=black};
title '3) Using border lines as a divider';
column section column1 column2 column3 column4 column5;
define section / order order=data noprint;
define column1 / "Column 1";
define column2 /  "Column 2";
define column3 /  "Column 3";
define column4 /  "Column 4";
define column5 /  "Column 5";
compute after section /
        style={height=1px bordertopcolor=black borderbottomcolor=black cellpadding=0
               bordertopstyle=solid borderbottomstyle=solid
               bordertopwidth=2pt borderbottomwidth=2pt};
  line ' ';
endcomp;
run;
ods _all_ close;

如果只需在section 1后面产生双线，不需要section 2后面的双线（最后的双线）, 应该怎样修改code? 谢谢！
