I closed my PR in favour of this one. It does more than was requested but that's a good thing.

NOTE:
Note that both this implementation and the alternative are not completely correct when it comes to accessibility. The information should really be in the caption element

I like this feature, tested and it works perfectly.

What do you think about using a badge?

@brianteeman I first had the same thought as you but cannot find a rule which requires presenting the information in the caption. Do you have a link?

[brianteeman]

A table caption is intended to describe a table - if we include how the table is sorted and filtered in that description (we do) then by the same toke we should include how many items are in the table.

I have tested this item ✅ successfully on d7794ad

Better to have it and it not be perfect for accessibility than not have it at all.
