Full width table help

Hi, thank you so much, i did it.. the only thing that i don’t understand is why i can see borders on top and bottom of the rows… i added this code but i can stil see the borders: .tablepress-id-N,
.tablepress-id-N tr,
.tablepress-id-N tbody td,
.tablepress-id-N thead th,
.tablepress-id-N tfoot th {
border: none;
}
