Hi,
ok, in your style.css file on line 6840 you have
.tcvpb-table td{
border-left: 1px solid #eeeeee;
border-top: 1px solid #eeeeee;
padding: 4px 20px !important;
}
please replace that with
.tcvpb-table td{
border-top: 1px solid red;
padding: 4px 20px !important;
border-left: 1px solid red !important;
border-right: 1px solid red !important;
}
And below that paste this code:
.tcvpb-table.table_border td{
border-bottom:1px solid red !important;
}
.tcvpb-table.table_border td:first-child{
border: none;
border-top:1px solid red;
}
.tcvpb-table.table_border td:last-child{
border: none;
border-top:1px solid red;
}
.tcvpb-table.table_border td {
border-top: 1px solid red !important;
border-bottom: 1px solid red !Important;
}
Please be sure that you add class named table_border in that section in Advanced tab.
I hope this help you :)
Cheers
