+ * <p>Ext.ListView is a fast and light-weight implentation of a\r

+ * <div class="mdetail-params"><ul>\r
+ * <li>resizable columns</li>\r
+ * <li>selectable</li>\r
+ * <li>column widths are initially proportioned by percentage based on the container\r
+ * width and number of columns</li>\r
+ * <li>uses templates to render the data in any required format</li>\r
+ * <li>no horizontal scrolling</li>\r
+ * <li>no editing</li>\r
