Describe the bug

select rows on a large btable introduce a ton of cell re-rendering even for unrelated rows, resulting in poor performance.

Steps to reproduce the bug

1. Go to https://jsfiddle.net/wk8zd50e/
2. Click on one or more rows
3. See the sloppiness of the select update

Expected behavior

I would expect the selected row to be shown instantly, I would expect to see in the vue dev-tools the re-rendering of the affected rows only, not the whole table
