NAME
       HTML::TableParser::Table - support class for HTML::TableParser

DESCRIPTION
       This class is used to keep track of information related to a table and to create the
       information passed back to the user callbacks.  It is in charge of marshalling the
       massaged header and row data to the user callbacks.

       An instance is created when the controlling TableParser class finds a "<table" tag.  The
       object is given an id based upon which table it is to work on.  Its methods are invoked
       from the TableParser callbacks when they run across an appropriate tag ("tr", "th", "td").
       The object is destroyed when the matching "/table" tag is found.

       Since tables may be nested, multiple HTML::TableParser::Table objects may exist
       simultaneously.  HTML::TableParser uses two pieces of information held by this class --
       ids and process.  The first is an array of table ids, one element per level of table
       nesting.  The second is a flag indicating whether this table is being processed (i.e. it
       matches a requested table) or being ignored.  Since HTML::TableParser uses the ids
       information from an existing table to initialize a new table, it first creates an empty
       sentinel (place holder) table (by calling the HTML::TableParser::Table constructor with no
       arguments).

       The class handles missing "/tr", "/td", and "/th" tags.  As such (especially when handling
       multi-row headers) user callbacks may be slightly delayed (and data cached).  It also
       handles rows with overlapping columns
