For a gentle introduction to multi-valued columns, look here.

Before you can use multi-valued columns, in hashed files or in UV tables, you have to enable them in the metadata. Because none of yours have multi-valued columns defined, the "normalize on" button is disabled.

If you did have multi-valued columns, then using the "normalize on" button has the same effect as using the UNNEST operator in a query, which is discussed in the post to which I referred you earlier.
