I want to create a table similar to what notion.so provides.

The great thing I love about this table is it is very dynamic. The highlighted part (in red) in the image is what I am specifically looking for. I want my table to have variable rows and columns (depending on what users might enter).

So my question is, is there a library or some kind of snippet that I can use that is already available?

I am using Angular 8 to make this and I already have Angular Material, AgGrid as existing dependencies.

I am open to any libraries.
