    The sequence of rows is significant.

    Explanation:

    The relational tables have the following characteristics:

    Column values are of the same kind. Each row is distinct and there are no duplicate rows. Each column has a unique name which is used to reference that column. The sequence of rows or columns is insignificant.

    That means that if I have a table consisting of 2 rows R1 and R2 then the sequence of R1 and R2 is immaterial.
