The size of Betti tables of edge ideals arising from bipartite graphs

Let $\operatorname{pd}(I(G))$ and $\operatorname{reg}(I(G))$ respectively denote the projective dimension regularity of edge ideal $I(G)$ a graph $G$. For any positive integer $n$, we determine all pairs $(\operatorname{pd}(I(G)),\, \operatorname{reg}(I(G)))$ as $G$ ranges over connected bipartite graphs on $n$ vertices.
