We can add borders to the table through css.

Method 1: Set the border only for the table label

table{
	border: 1px solid red;
}

##Method 2: Set border for td

Set the border style for the table td. The td within the table object will implement the border style, but the middle td will cause double borders.

Grammar:

td{
border: 1px solid red;
}

table {
        border-collapse: collapse;
        
}
