+1 for this feature.
I would use this in probably 50% of our table components.
Even more valuable if we could pick one column as a group and re-order within the group, would be really powerful when working with 50+ rows in a table. I’ve been using JS handlers to manage so far with up down buttons in rows, this eliminates the need for a re-order modal but its painful if you need to move a row from the bottom to the top of a table with 50 rows.
Drag and drop rows within the table component is probably not an easy feat but it will add a lot of value to end users!
