TablePress: Add table border in colour

I tried to add table border in colour but didnt work. I used the below code to do it column wise:

.tablepress-id-3 .column-1 {
width: 40px;
border: 1px solid #ffcc00;
}

.tablepress-id-3 .column-2 {
width: 180px;
border: 1px solid #ffcc00;
}

.tablepress-id-3 .column-3 {
width: 180px;
border: 1px solid #ffcc00;
}

.tablepress-id-3 .column-4 {
border: 1px solid #ffcc00;
}

.tablepress-id-3 .column-5 {
border: 1px solid #ffcc00;
}

But for the right and bottom lines of the table, border is not applied. Can you please help!!!
