Problem wile EXECUTE IMMEDIATE DDL statement in procedure

Question

Hi ,
This is my procedure and it's getting compiled but while executing procedure getting this error,
can anyone please tell me how to fix this?
create or replace procedure construct_Table (name_table IN VARCHAR2)
IS
v_tab_name varchar2(40):=NULL;
v_sql_Stmt varchar2(32767) := NULL;
finalquery varchar2(32767) :=NULL;
cursor tp is
select COLUMN_NAME,DATA_TYPE,DATA_PRECISION,CHAR_LENGTH  from all_tab_cols where table_name=name_table;
BEGIN
begin
select TABLE_NAME into v_tab_name from user_tables where table_name=name_table;
EXCEPTION
WHEN no_Data_found
THEN
DBMS_OUTPUT.PUT_LINE('No such table exist');
end;
if(v_tab_name IS NOT NULL)then
finalquery := 'CREATE TABLE '||v_tab_name||'_DUMMY (';
   FOR I IN tp LOOP
   if(I.data_type='VARCHAR2') then
   v_sql_stmt := finalquery ||I.column_name||' '||I.data_type||'('||I.char_length||') ';
   elsif(I.data_type='NUMBER') then
   v_sql_stmt := finalquery ||I.column_name||' '||I.data_type||'('||I.DATA_PRECISION ||') ';
   else
   v_sql_stmt := finalquery ||I.column_name||' '||I.data_type ;
   end if;
   finalquery := v_sql_stmt || ',';
   END LOOP;
   finalquery := SUBSTR(finalquery,1,LENGTH(finalquery) - 1)||')';
   dbms_output.put_line(finalquery);
   EXECUTE IMMEDIATE'grant create any table to cmsuser';
   EXECUTE IMMEDIATE finalquery;
end if; 
END;
/This is the error I am getting
Error starting at line 1 in command:
begin
construct_Table ('EMP');
end;
Error report:
ORA-01031: insufficient privileges
ORA-06512: at "CMSUSER.CONSTRUCT_TABLE", line 30
ORA-06512: at line 2
01031. 00000 -  "insufficient privileges"
*Cause:    An attempt was made to change the current username or password
           without the appropriate privilege. This error also occurs if
           attempting to install a database without the necessary operating
           system privileges.
           When Trusted Oracle is configure in DBMS MAC, this error may occur
           if the user was granted the necessary privilege at a higher label
           than the current login.
*Action:   Ask the database administrator to perform the operation or grant
           the required privileges.
           For Trusted Oracle users getting this error although granted the
           the appropriate privilege at a higher label, ask the database
           administrator to regrant the privilege at the appropriate label.Thanks ,

Deekay,
If you grant create table privilege and create table in the same procedure, then how you will differentiate that which user you granted the privilege and in which schema, you are creating the table. Here, you are granting to "cmuser", but in the same schema, you are creating the table also. How can a user grant privilege to himself?
Login as DBA, grant create any table privilege to "cmuser" from dba. Then, you can execute you procedure in "cmuser" schema.
