Datatable insertion order

[jackstuard]

Hello,

I have a case where I need to insert a items to the beginning of a datatable (imagine a case where the user choose a role from a autocomplete and add it to List, that will appear in a datatable).
My doubt is, how can I make the last item added appear on top of the datatable?
I see some scenarios but I'm curious to know if there is a better approach:

1. Use list.add(0, myObject);
or
2. Create a wrapper object that has a field called insertedDateTime then use the sortBy param from dataTable.

Any suggestion?

1: works 'now'
2: will keep working in the future to if you don't add a wrapper but add it to the model.
