EDIT 7/30/19 As @titou10 mentioned, there is no index field within Vuetify 2.0.

After looking around for a bit I was able to achieve this by utilizing the item.<name> slot. This slot will return me an item. I created an array of IDs based on the object id and called indexOf(item.id) to get the index position.

Vuetify 1.x

Each one of your props object contains two keys: item and index. You can access the index for each item by doing props.index. Adding a new header is as easy as adding a new item to your headers array.

Here is a codepen as an example. I am changing the first column of the data-table to the index position.
