Dynamically Add Another Table Once Text Fields In The Existing Table Is Clicked On?

how I would dynamically add another table once text fields in the existing table is clicked on. So pretty much what I have is a table with 5 textboxes lined up horizontally in the first row along with couple of buttons in the second row. What I want is that once one text box is clicked, another table like the one above is created and appears below that initial table. So this is the inital table that should be replicated on each click:

<table>
<tr>
<td><input type="text" /></td>
<td><input type="text" /></td>
<td><input type="text" /></td>
<td><input type="text" /></td>
<td><input type="text" ></td>
[Code]...
