How does one customize the table of listings for a custom post type?

1. it’s similar to adding columns to regular posts, except the filter and action are slightly different: manage_edit-{$post_type}_columns and manage_{$post_type}_posts_custom_column

   function wpse27787_add_video_column( $columns ){
       // add a new column to array of columns
       // can also unset columns here to remove them
       $columns['length'] = __('Length');
       return $columns;
   }
   
   function wpse27787_manage_video_columns( $column_name, $id ){
       // if this is our custom column, fetch whatever data we want to output
       if( $column_name == 'length' ):
           // get your video length here using this post's $id and
           echo $this_length;
       endif;
   }   
   
   function wpse27787_init() {
       // add our filter and action on admin_init
       add_filter( 'manage_edit-video_columns', 'wpse27787_add_video_column' );
       add_action( 'manage_video_posts_custom_column', 'wpse27787_manage_video_columns', 10, 2 );
   }
   add_action( 'admin_init' , 'wpse27787_init' );
   

   EDIT –

   if you want to reorder the columns, create a new array with the values from the original, adding your column in the desired position:

   function wpse27787_add_video_column( $columns ){
   
       foreach( $columns as $key => $val):
           $reordered_columns[$key] = $val;
           if( $key == 'title' ):
               // add our custom column after title
               $reordered_columns['length'] = __('Length');
           endif;
       endforeach;
   
       return $reordered_columns;
   }
