datatable types

hello, guys, i have an issue i am having for several days. I wanted to make a table component using useTable hook from "@refinedev/react-table" Basically, the columns field don't want to accept ColumnDef<TData>[] type value. It gives me: ColumnDef<TData, any>[]' is not assignable to type 'ColumnDef<BaseRecord, any>[] but if I try to hard code the columns to a type ColumnDef<BaseRecord, any>[] , it errors: Type 'BaseRecord' is not assignable to type 'TData'. Please help me

Hi @Amka. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To address your issue with the useTable hook from @refinedev/react-table, it seems you're encountering a type mismatch between TData and BaseRecord. Let's clarify this based on the information from the knowledge sources: The useTable hook in @refinedev/react-table expects the columns to be of type ColumnDef<TData>[], where TData extends BaseRecord. This is evident from the type parameters documentation for useTable: useTable Type Parameters To resolve your issue, you need to ensure that your TData type extends BaseRecord. Here's how you can approach this: 1. Define your data interface to extend BaseRecord:

interface IProduct extends BaseRecord {
  name: string;
  price: string;
  // other fields...
}

interface IProduct extends BaseRecord {
  name: string;
  price: string;
  // other fields...
}

2. Then, use this interface when defining your columns and calling useTable:

const columns = React.useMemo<ColumnDef<IProduct>[]>(
  () => [
    {
      id: "id",
      header: "ID",
      accessorKey: "id",
    },
    {
      id: "name",
      header: "Name",
      accessorKey: "name",
    },
    {
      id: "price",
      header: "Price",
      accessorKey: "price",
    },
    // other columns...
  ],
  []
);

const { getHeaderGroups, getRowModel } = useTable<IProduct>({
  columns,
  refineCoreProps: {
    resource: "products",
  },
});

const columns = React.useMemo<ColumnDef<IProduct>[]>(
  () => [
    {
      id: "id",
      header: "ID",
      accessorKey: "id",
    },
    {
      id: "name",
      header: "Name",
      accessorKey: "name",
    },
    {
      id: "price",
      header: "Price",
      accessorKey: "price",
    },
    // other columns...
  ],
  []
);

const { getHeaderGroups, getRowModel } = useTable<IProduct>({
  columns,
  refineCoreProps: {
    resource: "products",
  },
});

By defining your data interface (IProduct in this example) to extend BaseRecord, you ensure that it satisfies the type constraints of useTable. This approach should resolve the type mismatch you're experiencing. The key is to make sure your data type extends BaseRecord, which is the base type expected by refine's data hooks. If you're still encountering issues after trying this approach, please provide more details about your specific implementation, including your data interface and how you're importing BaseRecord. useTable API Reference TanStack Table Usage ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
