HTML & CSS - HTML TABLES - Cell span for many rows

Cell span for many rows

For making a cell span more than one row,we use the rowspan.
<!DOCTYPE html>
table, th, td {
    border: 1px solid black;
    border-collapse: collapse;
th, td {
    padding: 5px;
    text-align: left;    
<h2>Cell that spans two rows:</h2>
<table style="width:50%">
    <th rowspan="2">Telephone:</th>
