Introduction to HTML Tables

An example with row and column spanning:

	average		other category
	height	weight
males	1.9	0.003
females	1.7	0.002

This is represented as:

    <table border>
        <tr><th rowspan=2><th colspan=2>average
            <th rowspan=2>other<br>category
        <tr><th>height<th>weight
        <tr><th align=left>males<td>1.9<td>0.003
        <tr><th align=left>females<td>1.7<td>0.002
    </table>
