  For a family $\mathcal{F}\subseteq \omega^\omega$ we define the ideal
$\mathcal{I}(\mathcal{F})$ on $\omega\times\omega$ to be the ideal generated by
the family $\{A\subseteq \omega\times\omega:\exists f\in
\mathcal{F}\,\forall^\infty n\, (|\{k:(n,k)\in A\}|\leq f(n))\}.$ Using ideals
of the form $\mathcal{I}(\mathcal{F})$, we show that the structure of Borel
ideals in-between two well known Borel ideals $\mathcal{ED} =
\{A\subseteq\omega\times\omega:\exists m \, \forall^\infty n\, (|\{k:(n,k)\in
A\}|<m))\}$ and $\mathrm{Fin}\otimes\mathrm{Fin} =
\{A\subseteq\omega\times\omega:\forall^\infty n \, (|\{k:(n,k)\in
A\}|<\aleph_0))\}$ in the Kat\v{e}tov order is fairly complicated. Namely,
there is a copy of $\mathcal{P}(\omega)/\mathrm{Fin}$ in-between $\mathcal{ED}$
and $\mathrm{Fin}\otimes\mathrm{Fin}$, and consequently there are increasing
and decreasing chains of length $\mathfrak{b}$ and antichains of size
$\mathfrak{c}$.
