I found this cool source of a dynamic form but after trying to fitting it to using a table it won't work as intended. A little help?
<html>
<head>
<script language="Javascript" type="text/javascript">
//Add more fields dynamically.
function addField(area,field)
{
if(!document.getElementById) return; //Prevent older browsers from getting any further.
var field_area = document.getElementById(area); //Select area.
var all_inputs = field_area.getElementsByTagName("input"); //Get all the input fields in the given area.
//Find the count of the last element of the list. It will be in the format '<field><number>'.
var last_item = all_inputs.length - 1;
var last = all_inputs[last_item].id;
var count = Number(last.split("_")[1]) + 1;
//Create new element
if(document.createElement)
{
//W3C method.
var tr = document.createElement("tr");
var td = document.createElement("td");
var li = document.createElement("li");
var input = document.createElement("input");
input.id = field+count;
input.name = field+count;
input.type = "text"; //Type of field - can be any valid input type like text,file,checkbox etc.
li.appendChild(input);
td.appendChild(li);
tr.appendChild(td);
field_area.appendChild(tr);
}
else
{
//Older Method
field_area.innerHTML += "<tr><td><li><input name='"+(field+count)+"' id='"+(field+count)+"' type='text' /></li></td></tr>";
}
}
</script>
</head>
<body>
<div style="float: left; padding: 10px; width:20%;">
<fieldset>
<legend>
<h3>Booking Information</h3>
</legend>
<form name="newbookform1" method="POST">
<strong>What:</strong><br/>
<table align="left" border="0" cellspacing="0" cellpadding="3">
<ul id="what_area">
<tr><td><li><input type="text" name="item_1" id="item_1" /> </li> </tr></td>
<tr><td><li><input type="text" name="item_2" id="item_2" /> </li> </tr></td>
</ul>
<tr><td><input type="button" value="Add What Field" onclick="addField('what_area','item_');" /> </tr></td>
</table>
</form>
</fieldset>
</body>

If only it would work.
