Web / TanStack Interview Questions
How do you render custom Vue components inside TanStack Table cells?
The cell column definition accepts a function returning a string, VNode, or component. FlexRender handles all three transparently so you never need conditional render logic.
<script setup lang="ts">
import { h, defineComponent, computed } from "vue"
import {
useVueTable, createColumnHelper, getCoreRowModel, FlexRender,
} from "@tanstack/vue-table"
type Order={ id:number; status:string; amount:number }
const StatusBadge=defineComponent({
props:{ status:String },
setup(props){
const colour=computed(()=>({
paid:"bg-green-100 text-green-800",
pending:"bg-yellow-100 text-yellow-800",
cancelled:"bg-red-100 text-red-800",
}[props.status??"pending"]??"bg-gray-100"))
return ()=>h("span",{class:colour.value},props.status)
},
})
const ch=createColumnHelper<Order>()
const columns=[
ch.accessor("status",{
header:"Status",
cell: info=>h(StatusBadge,{status:info.getValue()}),
}),
ch.accessor("amount",{
header:"Amount",
cell: info=>`$${info.getValue().toFixed(2)}`,
}),
ch.display({
id:"actions",
header:"Actions",
cell: ({row})=>h("div",null,[
h("button",{onClick:()=>editOrder(row.original)},"Edit"),
h("button",{onClick:()=>deleteOrder(row.original.id)},"Delete"),
]),
}),
]
