How to rewrite $left[ begin{array}{c|c} I_{r}otimes (K e_1) \ vdots\ I_{r}otimes (K e_n) end{array} right]$?

I have the following matrix: $left[
begin{array}{c|c}
I_{r}otimes (K e_1) \
vdots\
I_{r}otimes (K e_n)
end{array}
right]$
$e_i$ is the i-th column of the identity matrix with the same dimensions as $K_{ntimes n}$. $otimes$ is the kronecker product.
I want to rewrite it in a way that $K$, or $vec(K)$, etc., is outside.

$K$ is the field you are working over?

Here's my try.
$(I_notimes I_rotimes K))left[
begin{array}{c|c}
I_{r}otimes e_1 \
vdots\
I_{r}otimes e_n
end{array}
right]$
