Progressive index in read only grid

Ooooh this is a fun question! I think your best bet here is to use the information in fv!currentPage, since that has the start index and identifiers of the current page. Here's an example column for how I was able to get it to work:

a!gridColumn(
  label: "Index",
  value: fv!currentPage.startIndex - 1 + wherecontains(fv!identifier, tointeger(fv!currentPage.identifiers))
)

fv!currentPage,

Wow, somehow I'd always missed that this is a thing that can be used in the Value parameter in a!gridColumn().  I note that the only place it's mentioned in the documentation (like, at all) is in the Validations parameter for the whole grid.

Yep, it's pretty useful! I'll see if we can get the documentation updated to make it more clear where you can use it
