-- Arrange output into tables.
--
-- This module provides NSE scripts with a way to output structured tables
-- similar to what <code>NmapOutputTable.cc</code> provides.
--
-- Example usage:
-- <code>
-- local t = tab.new()
-- tab.add(t, 1, 'A1')
-- tab.add(t, 2, 'A2')
-- tab.nextrow(t)
-- tab.add(t, 1, 'BBBBBBBBB1')
-- tab.add(t, 2, 'BBB2')
-- tab.nextrow(t)
-- tab.addrow(t, 'C1', 'C2')
-- tab.dump(t)
-- </code>
--
-- <code>tab.add</code> works on the bottom-most row until
-- <code>tab.nextrow</code> is called. Think of <code>tab.nextrow</code> as
-- typing Enter at the end of a line. <code>tab.addrow</code> adds a whole row
-- at a time and calls <code>tab.nextrow</code> automatically.
--
-- @copyright Same as Nmap--See http://nmap.org/book/man-legal.html
