/**
* Create a new customuserfieldtable object.
*
* @param mixed $items array (or other iterable) of items to be displayed
* in the table. Each element in the array should be an object, with
* fields matching the names in {@var $columns} containing the data.
* @param array $columns mapping of column IDs to column configuration.
* The column configuration is an array with the following entries:
* - header (optional): the plain-text name, used for the table header.
* Can either be a string or an array (for headers that allow sorting on
* multiple values, e.g. first-name/last-name). If it is an array, then
* the key is an ID used for sorting (if applicable), and the value is
* an array of similar form to the $columns array, but only the 'header'
* and 'sortable' keys are used. (Defaults to empty.)
* - display_function (optional): the function used to display the column
* entry. This can either be the name of a method, or a PHP callback.
* Takes two arguments: the column ID, and the item (from the $items
* array). Returns a string (or something that can be cast to a string).
* (Defaults to the get_item_display_default method, which just returns
* htmlspecialchars($item->$column), where $column is the column ID.)
* - decorator (optional): a function used to decorate the column entry
* (e.g. add links, change the text style, etc). This is a PHP callback
* that takes three arguments: the column contents (the return value from
* display_function), the column ID, and the item. (Defaults to doing
* nothing.)
* - sortable (optional): whether the column can be used for sorting. Can
* be either true, false, display_table::ASC (which indicates that
* the table is sorted by this column in the ascending direction), or
* display_table::DESC. This has no effect if the header entry is an
* array. (Defaults to the return value of is_sortable_default, which
* defaults to true unless overridden by a subclass.)
* - wrapped (optional): whether the column data should be wrapped if it is
* too long. (Defaults to the return value of is_column_wrapped_default,
* which defaults to true unless overridden by a subclass.)
* - align (optional): how the column data should be aligned (left, right,
* center). (Defaults to the return value of get_column_align_default(),
* which defaults to left unless overridden by a subclass.)
* @param moodle_url $base_url base url to the page, for changing sort
* order. Only needed if the table can be sorted.
* @param string $sort_param the name of the URL parameter to add to
* $pageurl to specify the column to sort by.
* @param string $sortdir_param the name of the URL parameter to add to
* $pageurl to specify the direction of the sort.
* @param array $attributes associative array of table attributes like:
* 'id' => 'tableid', 'width' => '90%', 'cellpadding', 'cellspacing' ...
