You have to write your own template that is based on the datagrid-template:
<?python
def get_class_for_value(v):
if v > 0:
return "green_class"
return "red_class"
?>
<div xmlns:py="http://purl.org/kid/ns#";>
<table id="${name}" class="grid" cellpadding="0" cellspacing="1" border="0">
<thead py:if="columns">
<tr>
<th py:for="i, col in enumerate(columns)" class="col_${i}">
${col.title}
</th>
</tr>
</thead>
<tr py:for="i, row in enumerate(value)" class="${i%2 and 'odd'
or 'even'}">
<td py:for="col in columns"
class="${get_class_for_value(col.get_field(row))}" >
${col.get_field(row)}
</td>
</tr>
</table>
</div>
