Try to find a row with the specified row key, or using the specified `lookup` parameter, and return the found row together with its actual key in case `lookup` was used. In case the row is not found, `OptionalValue.Missing` is returned. ## Parameters - `rowKey` - Specifies the key of the row to be returned - `lookup` - Specifies how to find value in a frame with ordered rows when the key does not exactly match (look for nearest available value with the smaller/greater key).
