Missing type file for WebStorm?

[YeBytes]

When I use "#-cell" slot in vue3.5.42 + NuxtUI4.9 and WebStorm2026.2.1, The IDE of WebStorm point out "Unrecognized slot name".
The codes:
`<script setup lang="ts">
import type { TableColumn } from "@nuxt/ui";

const data = [
{
price: 1,
quantity: 2,
},
{
price: 4,
quantity: 5,
},
];
const columns: TableColumn<{ price: number; quantity: number }>[] = [
{ accessorKey: "price", header: "价格" },
{ accessorKey: "quantity", header: "成本" },
];
</script>

{{ row.original.price.toFixed(2) }} `

Nothing is actually missing on the Nuxt UI side — the slot is typed, it's WebStorm's own Vue inspection that can't see it.

UTable builds its dynamic slot names from your row type with template-literal types (src/runtime/components/Table.vue):

type DynamicCellSlots<T, K = keyof T> = Record<`${K extends string ? K : never}-cell` | (string & {}), (props: CellContext<T, unknown>) => VNode[]>

So for { price: number; quantity: number } you get price-cell / quantity-cell (plus any other string, since column ids don't have to be keys of the row), and #price-cell type-checks fine with vue-tsc / nuxi typecheck. WebStorm's Unrecognized slot inspection (VueUnrecognizedSlot) can't enumerate the keys of a generic Record like this, so it flags the slot anyway — the same thing has been reported for other components in #5664.

Options:

• Try Settings | Languages & Frameworks | TypeScript | Vue → Enable service-powered type engine, which makes WebStorm use type information from the Vue Language Server and may resolve it.

• Otherwise suppress it for that tag:

  <!--suppress VueUnrecognizedSlot -->
  <template #price-cell="{ row }">
    {{ row.original.price.toFixed(2) }}
  </template>

  or disable it project-wide under Settings | Editor | Inspections | Vue | Unrecognized slot. It's only a weak warning and doesn't affect the build.

• If you want it fixed in the IDE, it's worth reporting on JetBrains YouTrack with this snippet — the fix belongs in WebStorm's Vue support rather than in Nuxt UI.
