In data provider for each sorting row define sorting rules:

    $dataProvider->sort->attributes['loadDate'] = [
        'asc' => ['status_load.status_time' => SORT_ASC],
        'desc' => ['status_load.status_time' => SORT_DESC],
    ];

    $dataProvider->sort->attributes['supplyingInvoiceNumber'] = [
        'asc' => ['cmd_delivery_osta.supplying_invoice_number' => SORT_ASC],
        'desc' => ['cmd_delivery_osta.supplying_invoice_number' => SORT_DESC],
    ];
