Create a table template. The DEFINE TABLE statement creates the table template Base.Standard.

proc template;
   define table Base.Standard;
      notes 'Table template for PROC Standard.';
      column name (mean std) n label;
      define name;  header='Name' varname='Name' style=RowHeader; end;
      define mean;  header='Mean/Std Dev' varname='Mean' format=D12.;
end;
      define std;   header='/Standard/Deviation'
         varname='stdDev' format=D12.; end;
      define n;     header='N' format=best.; end;
      define label; header='Label' varname='Label'; end;
      byline wrap required_space=3;
   end;
run;
 proc template;
   define tagset tagsets.myhtml;
        parent=tagsets.phtml;
        stacked_columns=no;
   end;
run;
