Hi @turansaim,
Please note, we’re not able to help directly with customizations per our [Support Policy](https://wpjobmanager.com/support-policy/), but only provide some general guidance. We’d recommend using CSS to achieve what you’re looking for. The extent of our documentation about CSS and WP Job Manager is here:
https://wpjobmanager.com/document/adding-custom-css-for-wp-job-manager/
Since so many themes override our CSS to varying extents, it’s not feasible for us to provide detailed documentation on modifying our plugin and addons with CSS.
That said, I found a somewhat related improvement request in our issue tracker to make the layout responsive:
https://github.com/Automattic/WP-Job-Manager/issues/1500
In the issue, one of our team members has provided a workaround in the form of CSS. I imagine you can modify the provided CSS in wp-admin > Appearance > Customize > Additional CSS to make the inserted table more mobile-friendly.
I hope that helps! Let us know if you have any other questions.
