An easier way to validate and work with table data

Use cases:

In a data table for example, elements of the same type can be shown. It would be handy to be able to count the number of elements of the same type.

Example 1: I added a record and I want to work on the last record/field. I don’t see a way to count the elements and then choose this number to find the last one.

Example 2: I want to check the number of elements shown to check if this is the same number as what's expected.

Example 3: I edited a field on the third row, after refreshing the page, I want to check if the same field in the third row was edited and has the correct value. I can find the field by value but I can’t check if it’s on the third row.

Example 4: I use drag and drop to order rows, I want to check if the 6th row is correct.
