The following code creates a two-column table, in which the first column lists the file titles and the second column contains the values of the custom field Author:
<table>
<npsobj list="toclist">
<tr><td>
<!-- Insert linked title-->
<b><npsobj name="self" insertvalue="anchor">
<npsobj name="title" insertvalue="var"/>
</npsobj></b>
</td>
<td>
<!-- Insert Author-->
<npsobj name="Author" insertvalue="var"/>
</td></tr>
</npsobj>
</table>
Of course you can also format the table using further HTML elements.
