   3   * RecordSet to HTML Table
   4   *
   5   * Convert a recordset to a html table. Multiple tables are generated
   6   * if the number of rows is > $gSQLBlockRows. This is because
   7   * web browsers normally require the whole table to be downloaded
   8   * before it can be rendered, so we break the output into several
   9   * smaller, faster rendering tables.
  10   *
  11   * This file is part of ADOdb, a Database Abstraction Layer library for PHP.
