Headers attribute test - multi level

Expected headers for target: "example 3 ltd, contact". Note: when using table navigation, screen readers will often reduce verbosity by not announcing headers multiple times; they will only announce changes to headers as you navigate through cells. Therefore, when navigating to the next column from the "contact" header, it is okay to only hear the "example 3 ltd" header. When navigating down from the "example 3 ltd" header, it is okay to only hear the "contact" header.
