/**

 * 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.
