It doesn't appear the Vuetify data table grouping handles the paging correctly when group headers are collapsed. If you want to collapse all group headers, you have to page through was appears to be empty pages until you get to the next group header.
<v-data-table
:headers="headers"
:items="stocks"
item-key="name"
sort-by="name"
group-by="sector"
class="elevation-1"
></v-data-table>
After collapsing the first header, I would think the next group header would appear with enough rows to fill the page. Instead, you have to page through several "empty" pages (the number of pages corresponds to the number of rows in the first grouping). How can I configure the grouping which will bring the next grouping into view when I collapse the previous grouping?
