Feature request: Allow double row

[cecheto]

Hi, it will be very interesting to be able to configure a double row, defining columns for each one, or at least been able to have fields spanned through columns in a different row. This will allow to have the descriptions or summaries in a different full width row.
I think it may be easily accomplished with a newrow and colspam attributes in the columns object attributes.
This will allow to have nice feeds like:
<tr><td><image></td><td>Title</td></tr><tr><td colspam=2>sumarry</tr>
