How about:
[pre]proc template ;
define table tabsas / STORE=SASUSER.TEMPLAT;
dynamic header_text footer_text ;
header head1 ;
column age sex height;
define head1; text header_text ; just=l;
split='/'; end;
define age; Header="age" just=c; just=c; end;
define sex ; Header="sex" just=c; just=c; end;
define height; Header="height" just=c; end;
end;
run;
ods rtf file="f:\mydoc.rtf";
data _null_;
set sashelp.class;
file print ods=( dynamic=(header_text="There is a way to increase
/the width of my table") template='tabsas');
put _ods_;
run;
ods rtf close;
