form with fields rendered in a table example

form_with_fields_in_table.php

<?php
/**
 * Example form using PW API 
 * 
 * A workaround to get fields display in a table
 * Those fields are marked with a property added to the fields $field->tablerow
 * 
 * Approach is to grab those fields after form is put together and maybe processed, 
 * loop each row and render out the fields along with possible errors and add it to a string variable $table
 * while we remove the field from the form at the same time.
 * Later we add that html back to the form using a markup inputfield (InputfieldMarkup).
 * 
 * This workaround allow to keep processing intact and show error validation for those fields, and have 
 * the form rendered in one call at the end.
