Could the sequence A287326 be generalized in order to receive expansion of natural power n>3?

The sequence https://oeis.org/A287326 - is Binomial distributed triangular array, that shows us necessary items to expand perfect cube n 3 n^3 . Summation of n n -th row of Triangle A287326 from 0 0 to n 1 n-1 returns n 3 n^3 . But is it exist simillar patterns in order to receive expansion of power n > 3 n>3 , where n n - positive integer?

1 1 1 1 7 1 1 13 13 1 1 19 25 19 1 \begin{matrix} & & & & & 1\\ & & & & 1 & & 1\\ & & & 1 & & 7& & 1\\ & & 1 & & 13& & 13& & 1\\ & 1 & & 19& & 25& & 19& & 1\\ \end{matrix}

    Figure 1. Triangle A287326.

It derived by means of identity

x 3 = m = 0 x 1 3 ! m x 3 ! m 2 + 1 x^3=\sum\limits_{m=0}^{x-1}3!\cdot mx-3!\cdot m^2+1
