If there's a table embedded in table, you get a WIN32OLERuntime error when iterating over the outer table with each(). If you iterate on the inner table it works properly. I've included some sample html and an IRB session snippet
Outer Table
irb(main):010:0> ie.tables[1].each { |t| puts t.class}
Watir::TableRow
Watir::TableRow
WIN32OLERuntimeError: unknown property or method `2'
