How to make automatic numbering of positions and subparagraphs in google sheets?

Question

Google Sheets

Is it possible to number subsections in google sheets?

What is the point. It is necessary that in the "No." field the number is automatically pulled up depending on the filling in the table.

Integers, if the "Resource" line is filled in, while the "Article" line should not affect the numbering.

But if the "Resource" remains empty, and the "Article" is filled, then sub-items should be formed, as in the example.

After skipping a few lines in the Resource, the "#" should drag on an integer.
