Css before page reload, after the code is edited in Webstorm and automatically compiled:

And after the reload:

And if I just remove the first row, the same happens no matter which one is first.

Answer 1

I had the same problem.

They problem here is that You override the items slot including <tr> tag. Without that everything will work fine. But for me, that was not a solution so if You want to override the <tr> tag also, add :key to it, like this: <tr :key="props.index">. Take a look at source of v-data-table here. To be honest, i don't know why it make that big difference but in my case that resolved the problem (i suspect that it is connected with vue list rendering).

Hope it helps!
