suppress the column of row headings in PROC TABULATE

[deleted_user]

Folks,
How would you remove completely the column of row headings (including the box) from the output of a PROC TABULATE? I searched this forum but couldn't find an answer.
For example In my program below, I want sheet 'a' to be identical to sheet 'b'. It's SAS 9.1.3 by the way.

data a;
do _n_=1 to 10;
x=ceil(3*ranuni(1));
y=ceil(4*ranuni(1));
z=ceil(2*ranuni(1));
output;
end;
ods _all_ close;
ods tagsets.excelxp file='c:\data\example.xls' style=minimal options(sheet_name='a');
proc format;
picture mypct(default=7)
0-100='009.99%%'
;
proc tabulate data=a;
class x y z;
table all='', (x y z)*(n='n'*f=1. pctn='%'*f=mypct.)/row=float indent=0;
run;

data b/view=b;
set a nobs=nobs;
retain weight;
if _n_=1 then weight=1/nobs;

ods tagsets.excelxp options(sheet_name='b');
proc report data=b nowd;
column (x--z),(n weight);
define x--z/across format=1.;
define weight/analysis '%' format=percent8.2;
run;
ods _all_ close;

If it cannot be suppressed, could you set column 1 hidden?
