Set type of table record using useTable
How do I set a type to my table records? I'm currently using Ant Design and the useTable() hook. What changes do I need to make in order to avoid the error commented in my code snippet?

Hi @Chrystian Ferreira. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

To set a type for your table records when using the
useTable
hook, you need to pass the type as a generic parameter to the useTable
function. This will ensure that TypeScript knows the type of the record
object in your render function.
Here's how you can do it:
First, define an interface for your record. For example, if your record has an id
and a name
, you can define it like this:
Then, pass this interface as a generic parameter to the useTable
function:
Now, TypeScript should know that record
is of type IRecord
, and you should be able to access record.name
without any TypeScript errors.
Here's your updated code:
For more information, you can refer to the useTable documentation (https://refine.dev/docs/ui-integrations/ant-design/hooks/use-table).

@kapa.ai This yields the same result. Looking at the 'render' prop, the type is the following:
Let me check the knowledge base for you. One moment! :books:
----------------------
The type definition you're seeing is coming from Ant Design's
Table.Column
component, not from the useTable
hook. The record
parameter in the render
function of Table.Column
is typed as unknown
by Ant Design, which is why you're seeing the TypeScript error.
To avoid this error, you can use a type assertion in the render
function to tell TypeScript that record
is of type IRecord
. Here's how you can do it:
In this code, const typedRecord = record as IRecord;
is a type assertion that tells TypeScript to treat record
as IRecord
. Now, you should be able to access typedRecord.name
without any TypeScript errors.

That would work, but I believe my solution is a bit more adequate:
AI should fear me
just kidding pls dont take my job
this solves the problem, i dont know how to mark this thread as solved

Hey @Chrystian Ferreira I think we have more time before AI takes over our jobs. I've marked your question as solved here, no worries.
