Use rowspan if you want to extend cells down and colspan to extend across.

If anyone is looking for a rowspan on both the left AND on the right, here is how you can do it:

table { 
    border-collapse: collapse;
}

td {
    padding: 20px; 
    border: 1px solid black; 
    text-align: center;
}

<table>
    <tbody>
    <tr>
        <td rowspan="2">LEFT</td>
        <td> 1 </td>
        <td> 2 </td>
        <td> 3 </td>
        <td> 4 </td>
        <td rowspan="2">RIGHT</td>
    </tr>
    <tr>
        <td> 5 </td>
        <td> 6 </td>
        <td> 7 </td>
        <td> 8 </td>
    </tr>
    <tr>
        <td> - </td>
        <td> - </td>
        <td> - </td>
        <td> - </td>
        <td> - </td>
        <td> - </td>
    </tr>
    </tbody>
</table>

Alternatively, if you want to add the LEFT and RIGHT to an existing rowset, you can achieve the same result by throwing them in with a collapsed colspan in between:

table {
    border-collapse: collapse;
}

td {
    padding: 20px; 
    border: 1px solid black; 
    text-align: center;
}

<table>
    <tbody>
    <tr>
        <td rowspan="3">LEFT</td>
        <td colspan="4" style="padding: 0; border-bottom: solid 1px transparent;"></td>
        <td rowspan="3">RIGHT</td>
    </tr>
    <tr>
        <td> 1 </td>
        <td> 2 </td>
        <td> 3 </td>
        <td> 4 </td>
    </tr>
    <tr>
        <td> 5 </td>
        <td> 6 </td>
        <td> 7 </td>
        <td> 8 </td>
    </tr>
    <tr>
        <td> - </td>
        <td> - </td>
        <td> - </td>
        <td> - </td>
        <td> - </td>
        <td> - </td>
    </tr>
    </tbody>
</table>

Colspan and Rowspan A table is divided into rows and each row is divided into cells. In some situations we need the Table Cells span across (or merged) more than one column or row. In these situations we can use Colspan or Rowspan attributes.

Colspan The colspan attribute defines the number of columns a cell should span (or merge) horizontally. That is, you want to merge two or more Cells in a row into a single Cell.

<td colspan=2 >

How to colspan ?

<html>
<body >
    <table border=1 >
        <tr>
            <td colspan=2 >
                Merged
            </td>
        </tr>
        <tr>
            <td>
                Third Cell
            </td>
            <td>
                Forth Cell
            </td>
        </tr>
    </table>
</body>
</html>

Rowspan The rowspan attribute specifies the number of rows a cell should span vertically. That is , you want to merge two or more Cells in the same column as a single Cell vertically.

<td rowspan=2 >

How to Rowspan ?

<html>
<body >
    <table border=1 >
        <tr>
            <td>
                First Cell
            </td>
            <td rowspan=2 >
                Merged
            </td>
        </tr>
        <tr>
            <td valign=middle>
                Third Cell
            </td>
        </tr>
    </table>
</body>
</html>

You can use rowspan="n" on a td element to make it span n rows, and colspan="m" on a td element to make it span m columns.

Looks like your first td needs a rowspan="2" and the next td needs a colspan="4".

<style type="text/css">
     table { border:2px black dotted; margin: auto; width: 100%; }
    tr { border: 2px red dashed; }
    td { border: 1px green solid; }
</style>
<table>
    <tr>
        <td rowspan="2">x</td> 
        <td colspan="4">y</td>
    </tr>
    <tr>
        <td>I</td>
        <td>II</td>
        <td>III</td>
        <td>IV</td>
    </tr>
    <tr>
        <td>nothing</td>
        <td>1</td>
        <td>2</td>
        <td>3</td>
        <td>4</td>
