I have below code

$this->addColumn(
                    'qty[]', [
                'header' => __('Qty'),
                'type' => 'number',
                'index' => 'qty',
                'editor' => 'text',
                'class' => 'validate-number',
                    ]
            );

How to validate this field. I need to validate for only numbers allowed?

Simply add:

'validate_class' => 'validate-number',

Take a look: vendor/magento/module-sales/Block/Adminhtml/Order/Create/Search/Grid.php
