The view you show in the image is a List view, which, somewhat annoyingly, are not currently sharable using external links in the way that other views are. 

Others have raised this issue in the past. For example the most liked comment in this post.

Thank you @Dominic11. I can't imagine why sharing isn't allowed in the List view. Doesn't seem like Airtable cares much about answering anyone. 

I want share button for list view, because I want to embed a tabla on my website. Why is this not possible? Why other views can be embedded on the website and this one cannot?

Yes, list views absolutely need to be shareable the same way other view types are! I finally came across a good use case for my organization to really leverage the list view functionality and built out exactly what we need -- only to discover it cannot be shared externally, which makes the whole thing pointless. ☹
