Sounds like your view is of type table. To custom theme the content of a 
column use a function template.php like:

function 
phptemplate_views_handle_field_node_data_FIELDNAME_FIELDNAME_value($fields, 
$field, $data)

This works for me anyhow. You may have to play with it to get the 
function name precise. To see this in the Views code, find function 
phptemplate_views_view_table and see the line:

         $cell['data'] = views_theme_field('views_handle_field', 
$field['queryname'], $fields, $field, $node, $view);

See the code in theme_views_handle_field and you will see how the Views 
module looks for custom functions to replace the default ones.
