JavaScript to get the number of rows and columns of a table

How can I use JavaScript to obtain the number of rows and columns in a table? In fact, it is very simple. Assume that the following table exists:

<table width="100%" border="1" cellspacing="0" cellpadding="0" id="example_table">    <tr>        <td>&nbsp;</td>        <td>&nbsp;</td>        <td>&nbsp;</td>        <td>&nbsp;</td>        <td>&nbsp;</td>    </tr>    <tr>        <td>&nbsp;</td>        <td>&nbsp;</td>        <td>&nbsp;</td>        <td>&nbsp;</td>        <td>&nbsp;</td>    </tr>    <tr>        <td>&nbsp;</td>        <td>&nbsp;</td>        <td>&nbsp;</td>        <td>&nbsp;</td>        <td>&nbsp;</td>    </tr></table>

The following code retrieves the number of rows and columns of the table:

// Table row var rows = document. getElementById ("example_table "). rows. length; // Number of table columns var cells = document. getElementById ("example_table "). rows. item (0 ). cells. length;
