Here's how you could display a table with variable number of rows and columns using
the Nested tags.
Assumptions:
o Bean name - aBean
o aBean contains a collection called rowCollection
o Each element in colCollection contains a collection called colCollection
<nested:root name="aBean">
<table>
<nested:iterate property="rowCollection">
<tr>
<nested:iterate property="colCollection">
<td>
<nested:write property="cellValue"/>
</td>
</nested:iterate>
</tr>
</nested:iterate>
<table>
</nested:root>
You will have to wrestle with colspan values if rows have different number of columns
or you'll have to pad the column collection with empty "cells".
Hope that helps
