rights_exchange_log表为权益兑换记录，关联了用户id(user_id)，需要根据用户手机号来查询用户兑换记录，期望的最终SQL如下：

SELECT
    * 
FROM
    `rights_exchange_log`
    LEFT JOIN `fk_member` ON `fk_member`.`id` = `rights_exchange_log`.`member_id` 
WHERE
    `fk_member`.`tel` = 12312321312

方法1：model中做下关联，controller层像普通变量直接查询过滤即

public function crmMember()
{
    return $this->belongsTo(\\App\\Models\\crm\\MemberModel::class, \'member_id\');
}

$grid->filter(function ($filter){
    $filter->like(\'crmMember.tel\', \'用户手机号\');
});

方法2：手动查询然后拼接条件

$grid->filter(function ($filter){
    $filter->where(function ($query) {
        $uid_list = \\App\\Models\\halo\\MemberModel::query()->where(\'mobile\', \'like\', "%{$this->input}%")->select(\'id\')->get()->toArray();
        $query->whereIn(\'member_id\', $uid_list);
    }, \'用户手机号\');
});

这种方法可以跨库查询，我实际场景rights_exchange_log在crm库，member在用户中心库，这种方法刚好适用
