A snippet which adds a custom column, and removes an existing column from the Events admin table

Thank you so much Stephen! This is really a big help. If someone needs the snippet for having the reoccurences listed in my way here we go.
The function first:

/**
 * Custom reoccurence list function
 */
function show_custom_reoccurence( $event_id, $max_display_count = 10, $max_reoccurrence_count = 24 )
{
        $occur_datelist = array();
        $occur_array =  eo_get_the_future_occurrences_of($event_id);

        if($occur_array)
        {
          //lets assume that to big list should be displayed by EO 
          if(count($occur_array) >= $max_reoccurrence_count)
          {
               eo_display_reoccurence( $event_id );
          }
          else //shorter ones will be listed by us 
          {
            foreach ($occur_array as $value) 
            {
                $date = $value["start"];    
                $occur_datelist[] = $date->format('d-m-Y');
            }
            //Shorten the Array when needed
            if(count($occur_datelist) > $max_display_count)
            {
                $list_overhead = count($occur_datelist)-$max_display_count;
                $occur_datelist = array_slice($occur_datelist, 0, $max_display_count);
                echo implode(", ", $occur_datelist )." ... (".$list_overhead."+)";
            }
            else
            {
              echo implode(", ", $occur_datelist );
            }
          }
        }
        else 
            echo "---";
}

Then change the function call in Stephens code from:

eo_display_reoccurence( $event_id );

To:

show_custom_reoccurence( $event_id );
