如何加入doctrine没有doctrine定义关系并且已连接表的实体在相同的数组索引下返回？

I am working on a query for two tables that do not have fk defined or orm relation but they are actually related. Example:

tableA: id, value

ROWS ((1, test), (2, test2))

tableB: id, tableA_id, value

ROWS ((1, 1, testIt))

I need to join them with doctrine and get the value of both tableA and tableB.

Currently i get

[
ObjectA(id=1),
ObjectB(id=1),
ObjectA2(id=2),
null
]

With DQL:

$queryBuilder
    ->select('ta')
    ->addSelect('tb')
    ->innerJoin(TableB::class, 'tableB', Join::WITH,
        'ta.id = tb.tableAId')
    ->getQuery()->getResult();

I need (not set in stone, need it do be grouped by join):

[
   [ObjectA(id=1), ObjectB(id=1)],
   [ObjectA(id=2)]
]
