这根本不起作用。

  function owner_columns($columns)
     {
        $columns[\'views\'] = \'Owner\';    
        return $columns;
     }  
     add_filter(\'manage_edit-listing_columns\', \'owner_columns\');

  function custom_posts_table_content( $column_name, $post_id )
    {   
      if( $column_name == \'Owner\' )
        {        
          echo \'Test\';      
      }

     }     
  add_action( \'manage_edit-listing_custom_column\', \'custom_posts_table_content\',10,2);
