Why doesn't the diagonal line produced by \diagbox touch the table cell corners?

Question

I was trying to use \diagbox, but It's not going from one corner to another corner in a cell (look on image). Anyone could help me? Please. Thanks.

Does this answer your question? How to diagonally divide a table cell … properly? — user202729, Mar 28 '23 at 12:02
(or Diagonal lines in table cell - TeX - LaTeX Stack Exchange, both has alternative solutions that allow diagonal lines at arbitrary slope) — user202729, Mar 28 '23 at 12:04
Actually maybe that's not the issue, the issue is that your cell is wider so just pass a larger width value to the command, should just work. — user202729, Mar 28 '23 at 14:02
Thanks everybody, the third comment solved my question. Thanks @user202729 for dedication. — Brendon Peres, Mar 28 '23 at 14:29

People, I only solved by using width parameter of \diagbox. Thanks @user202729.

\multirow{2}{*}{\diagbox[width=7em]{~}{~}} & \multicolumn{10}{c|}{2023} & \multicolumn{2}{c|}{2024} \\

Why doesn't the diagonal line produced by \diagbox touch the table cell corners?
