1 Columns, sorting, paging

Click a header to sort: ascending → descending → original order. "Owner" has no sort, so it is not a button. Type in the filter — the page and the sort stay, an empty result shows emptyMessage.

2 Selection and bulk actions

"Restart" runs at once, "Stop" asks for a reason, "Delete" asks for confirmation. Servers marked locked fail on purpose: the rest still run, and the result says "done N, failed M". The selection survives sorting and paging.

3 Row actions and highlight

Two icons in the row, the rest in the "⋮" menu, "Delete" last in red. On locked servers "Rename" and "Delete" are disabled. "Open" highlights the row while its details are shown.
