Tables the assistant can propose

When you add documents to an app, the assistant can now suggest a table to hold what's in them, with the columns it thinks you'll want. You look over the proposal, change anything that isn't right and accept it, and the rows fill in as each document is read. Once the table exists you can edit it directly in the grid, just like a spreadsheet, and anything the assistant couldn't confirm is marked so you know where to look.
