Use rowspan to span rows to several rows
Description
To span cell to multiple rows, you can use the rowspan attribute.
The value you assign to this attribute is the number of rows to span.
The values assigned to the rowspan must be integers.
If you want one cell in the middle column to span all three rows,
you apply the rowspan attribute to cell 2.
You also have to remove the cell elements that the expanded cell will cover.
Example
The following code expands a Cell to Cover Multiple Rows.
<!DOCTYPE HTML>
<html>
<head>
<style>
td {<!-- ww w. j a va 2s .c om-->
border: thin solid black;
padding: 5px;
font-size: x-large
}
</style>
</head>
<body>
<table border='1'>
<tr>
<td>1</td>
<td rowspan="3">2</td>
<td>3</td>
</tr>
<tr>
<td>4</td>
<td>6</td>
</tr>
<tr>
<td>7</td>
