I think this approach makes sense if we can get it to work. Until the table data has finished loading there is no need to load the table preferences IMO. I would ask that we update the logic for the menu trigger button to handle the other table states though (if we aren't already).

const tableState = computed((): TableState => isTableLoading.value ? 'loading' : fetcherError.value ? 'error' : 'success')

If tableState is loading lets disable the menu button; if it's error lets hide the button.

That's how it works already (column visibility and pagination controls are hidden when table is on loading or error states)
