Show entry id for each entry on overview page

Okay, I found this hook, that could help me display the entry id:

add_action('gform_entries_first_column', 'first_column_content', 10, 5);
function first_column_content($form_id, $field_id, $value, $lead, $query_string) {

	echo 'Entry id: <strong>'.$lead['id'].'</strong>';

}

This is not exactly what I was looking for but close enough.

I was actually looking to create a new column where the entry id would be displayed. But like I said, this is good enough. :-)

He he, I didn't know this was possible. Thanks Chris, for pointing this out. :-)
