Update index when filter is applied to table

[Christianvs]

Hi

I am trying to figure out the best way to implement a self updating index column and I asked a question yesterday that is related to this but in a slightly different fashion. 

My question here is whether I can implement a index column that updates whenever a filter is applied to the table the column exists in.
So I got an index column which I have added through Power Query Editor:

Now when I apply a filter to this table, some rows are not shown which means that the index isn't going from 1 to N (number of rows) anymore:

Is it possible to make a measure og a calculated column that updates everytime a filter is applied to the table so the index column always shows from 1 to N?

Thanks

Let the table containing the Index column be 'Index Table'

Try this measure:

New index =
RANKX (
    ALLSELECTED ( 'Index table' ),
    CALCULATE ( SUM ( 'Index table'[Index] ) ),
    ,
    ASC,
    DENSE
)
