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:
[ch_pre type="css"]thead,
tbody,
tfoot,
tr,
td,
th {
border-width: 1px;
}[/ch_pre]

This will definitely work fine. Hope this Helps!
