component-datatable.html not showing borderline on the left side of the table

Hello,

Thanks for reporting this. This appears to be related to the Bootstrap 5 update. Consider using the following CSS Code:

thead,
tbody,
tfoot,
tr,
td,
th {
    border-width: 1px;
}

This will definitely work fine. Hope this Helps!
