#values ⇒ Array<Google::Protobuf::ListValue>

Returns The values to be written. +values+ can contain more than one list of values. If it does, then multiple rows are written, one for each entry in +values+. Each list in +values+ must have exactly as many entries as there are entries in Columns above. Sending multiple lists is equivalent to sending multiple +Mutation+s, each containing one +values+ entry and repeating Table and Columns. Individual values in each list are encoded as described Here.
