I am wondering why it is not possible to prevent certain columns from being sortable. My grid is defined as sortable and as far as I understood the documentation I can specify a sortable-flag for each column separately. I prepared a small example where I want to exclude the product name column from sorting but you can still click on the column header and the sortchange handler is triggered. See the console output. Styling is interestingly not applied, i.e. the arrow does not appear there.
