/**
 * RecordSet to HTML Table
 *
 * Convert a recordset to a html table. Multiple tables are generated
 * if the number of rows is > $gSQLBlockRows. This is because
 * web browsers normally require the whole table to be downloaded
 * before it can be rendered, so we break the output into several
 * smaller, faster rendering tables.
 *
 * This file is part of ADOdb, a Database Abstraction Layer library for PHP.
