Function with table parameters Oracle - sql

Question

I have the below function. I would like to make it parametrisable. I would want to give as input parameters table_t5 and dunnv3_t6. Would this be possible? I know how to define functions with strings, numbers... as parameters but I'm struggling to pass tables as input parameters.
CREATE OR REPLACE FUNCTION dunnv3_ec_assign RETURN t5_table
PIPELINED
IS
TYPE t6_type IS
TABLE OF dunnv3_t6%rowtype;
t6_data t6_type;
v_cc table_t5.campaign_code%TYPE;
BEGIN

FOR cur IN (
logic which orders the input table for cursor processing
) LOOP
IF v_cc IS NULL OR v_cc <> cur.cc THEN
v_cc := cur.cc;
SELECT

BULK COLLECT
INTO t6_data
FROM
dunnv3_t6
WHERE
cc = cur.cc;
END IF;
DECLARE
a_freqs int_list := int_list();
cum_freq INT := 0;
taken string_list := split_string(cur.an, ', ');
idx INT;
c dunnv3_t6.a%TYPE;
BEGIN
a_freqs.extend(t6_data.count);
FOR i IN 1..t6_data.count LOOP IF ( t6_data(i).a = cur.ay AND t6_data(i).c > 0 ) OR ( cur.ay IS NULL AND t6_data(i).a
NOT MEMBER OF taken AND t6_data(i).c > 0 ) THEN
a_freqs(i) := cum_freq + t6_data(i).c;
cum_freq := cum_freq + t6_data(i).c;
ELSE
a_freqs(i) := cum_freq;
END IF;
END LOOP;
IF cum_freq > 0 THEN
idx := floor(dbms_random.value(0, cum_freq));
FOR i IN 1..t6_data.count LOOP IF idx < a_freqs(i) THEN
c := t6_data(i).a;
t6_data(i).c := t6_data(i).c - 1;
EXIT;
END IF;
END LOOP;
END IF;
PIPE ROW ( t5_data(cur.vk, cur.ay, cur.an, cur.cc, cur.r,
c) );
END;
END LOOP;
END;
CREATE TYPE t5_data AS OBJECT (
vk NVARCHAR2(12),
ay CHAR(10),
an VARCHAR2(4000),
cc VARCHAR2(5),
r NUMBER,
c CHAR(10)
);
CREATE TYPE t5_table IS
TABLE OF t5_data;
Oracle version 12.1. Kindly let me know if additional info required.
EDIT, I would also need the 'logic which logic which orders the input table for cursor processing to be passed as a parameter.
