If you mean something like this, then yes
http://eehowto.com/index.php/howto-2010/categories
{exp:channel:category_archive channel="howto" show_empty="no"}
{categories}<h3>{category_name}</h3>
<p>Number of entries: {exp:catcount cat_id="{category_id}" status="open|closed"}<br />
{/categories}</p>
<p>{entry_titles}<a href="http://{path=howto/articles}">{title}</a>{/entry_titles}</p>
<p>{/exp:channel:category_archive}
NOTE: I’m using a small plugin to count the number of entries.
Does that help?
Ordinarily this would be considered a howto or a Community Help forum question, but I had the code on hand to show you.
What if I wanted to include more than just the entry titles in the list?
something more like:
CATEGORY 1 NAME
title 1 customfield 1
title 2 customfield 2
title 3 customfield 3
CATEGORY 2 NAME
title 1 customfield 1
title 2 customfield 2
title 3 customfield 3
CATEGORY 3 NAME
title 1 customfield 1
title 2 customfield 2
title 3 customfield 3
