 * Create advanced table (resize, reorder, and show/hide columns; and also grid editing).

 * For using this function in other table DOM, you may need to:
 * - add "draggable" class in the table header <th>, in order to make it resizable, sortable or hidable
 * - have at least one non-"draggable" header in the table DOM for placing column visibility drop-down arrow
 * - pass the value "false" for the parameter "enableGridEdit"
 * - adjust other parameter value, to select which features that will be enabled
 *
 * @param t the table DOM element
 * @param enableResize Optional, if false, column resizing feature will be disabled
 * @param enableReorder Optional, if false, column reordering feature will be disabled
