Panic in Sort Merge Equijoin when tables have different columns count

[tglanz]

Related to #18787

Describe the bug

During sort merge join, with a filter, and the columns count of the left/right relations are different, the extracted columns is off which leads to datafusion error such as:

DataFusion error: Arrow error: Invalid argument error: number of columns(2) must match number of fields(4) in schema

To Reproduce

Following sqltests are failing

statement ok
set datafusion.optimizer.prefer_hash_join = false;

statement ok
DROP TABLE IF EXISTS t1;

statement ok
CREATE TABLE t1(a int, b int) AS VALUES (1, 100), (2, 200), (3, 300);

statement ok
DROP TABLE IF EXISTS t2;

statement ok
CREATE TABLE t2(a int, b int, c int) AS VALUES (4, 101, 1001), (3, 201, 2001), (2, 250, 3001);

statement ok
DROP TABLE IF EXISTS t3;

statement ok
CREATE TABLE t3(x int) AS VALUES (1);

query IIIII
SELECT * FROM t2 RIGHT JOIN t1 on t1.a = t2.a AND t1.b < t2.b
----
NULL NULL NULL 1 100
2 250 3001 2 200
NULL NULL NULL 3 300

query IIIII
SELECT * FROM t1 LEFT JOIN t2 on t1.a = t2.a AND t1.b < t2.b
----
1 100 NULL NULL NULL
2 200 2 250 3001
3 300 NULL NULL NULL

# Small table for LeftMark

# LeftMark equijoin with different columns count
query III rowsort
SELECT t2.a, t2.b, t2.c
FROM t2
WHERE t2.a > 3 OR t2.a IN (SELECT t3.x FROM t3 WHERE t2.b < 150)
----
4 101 1001
