Hello,
Since this is a 3rd Party Plugin: https://datatables.net/examples/styling/bootstrap4.html, you will need to use Custom Codes and modify these manually, as we currently do not provide Customization related Support according to the Item Support Policy: https://themeforest.net/page/item_support_policy .
As a starter, you can consider using the following code:
[ch_pre type="css"].dataTables_wrapper .row:nth-child(3) {
flex-direction: column;
align-items: center;
}
.dataTables_info {
margin-top: 1rem;
text-align: center;
}
div.dataTables_wrapper div.dataTables_paginate ul.pagination {
margin-top: 1.5rem;
justify-content: center;
}[/ch_pre]
Hope this Helps!
