Backport of a modification/addition to the customfield widget from Ralf

Browse Source 
pre_process_cf_header
 function to display the customfields in a nextmatch table-header with the functionality of sorting and selecting
 by customfields. Of cource you need to adapt the source of your get_rows or search functionality to do the
 actual sorting and selecting. We try to do some additional documentation in codecorner
 You can pass the allowed/wanted fields to the header by passing an array of the wanted fields to the widget
 through the options parameter (see the eTemplate editor for fields/cells). This array is passed on through
 $cell['size']. By now the array passed through is only working, if it is the only entry in the optionsparameter.
 The allowed fields array assumes an numerical indexed array of (an) array(s) with ['name'] tag(s) set. 
 The name provided assumes a preceding #. (e.g.: $allowed_fields[x]['name']='#MyCustomField')
