Enumeration on row-increasing tableaux of shape $2\times n$

Recently O. Pechenik studied the cyclic sieving of increasing tableaux of shape $2\times n$, and obtained a polynomial on the major index of these tableaux, which is a $q$-analogue of refined small Schr"{o}der numbers. We define row-increasing tableaux and study the major index and amajor index of row-increasing tableaux of shape $2\times n$. The resulting polynomials are both $q$-analogues of refined large Schr"{o}der numbers. For both results we give bijective proofs.
