Error with tables, not showing any data

Warning: [antd: Table] dataSource length is less than pagination.total but large than pagination.pageSize. Please make sure your config correct data with async mode. this only happens on the few last pages, except the very last one How can I debug this? or fix it

Hi @khadhulu. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- The warning you're seeing from Ant Design Table:

Warning: [antd: Table] dataSource length is less than pagination.total but large than pagination.pageSize. Please make sure your config correct data with async mode.

indicates a mismatch between the data provided to the table (dataSource), the total number of items (pagination.total), and the page size (pagination.pageSize). This often happens when the data returned for a page does not match the expected number of items, especially on the last few pages. Common Causes and Debugging Steps 1. Check API Response for Pagination - Ensure your API returns the correct number of items for each page, and that the total count is accurate. - For server-side pagination, the API should return: - An array of items for the current page (length ≤ pageSize) - The total number of items (e.g., via x-total-count header or a total field in the response)
See: Pagination in useTable
See: useList Pagination 2. Check DataProvider Implementation - If you use a custom data provider, make sure the getList method slices data correctly and returns the right total value. - If the last page has fewer items than pageSize, that's expected, but if a page in the middle has fewer, your slicing logic may be off. 3. Check Table Props - Make sure you are passing the correct pagination object to the <Table> component.
Example:

     <Table
       {...tableProps}
       rowKey="id"
       pagination={{
         ...tableProps.pagination,
         position: ["bottomCenter"],
         size: "small",
       }}
     />

     <Table
       {...tableProps}
       rowKey="id"
       pagination={{
         ...tableProps.pagination,
         position: ["bottomCenter"],
         size: "small",
       }}
     />

See: Ant Design useTable Pagination 4. Check for Async Data Issues - If you fetch data asynchronously, ensure that the dataSource and pagination.total are updated together and consistently. Why It Happens on the Last Few Pages - If your total is not a multiple of pageSize, the last page will have fewer items, which is fine. - If the second-to-last page (or others) has fewer items than pageSize, but the last page has the correct count, your API or data slicing logic may be off by one page. How to Fix - Verify API returns correct data and total for each page. - Ensure your data provider's getList method returns:

  {
    data: [...], // array of items for the current page
    total: 1322, // total number of items
  }

  {
    data: [...], // array of items for the current page
    total: 1322, // total number of items
  }

- Check that the pagination prop in <Table> matches the data. Additional Debugging - Log the data and pagination values before rendering the table to ensure they match expectations. - If using server-side pagination, check that the backend correctly implements the logic for _start, _end, limit, offset, etc. If you continue to have issues, try to reproduce the problem in a minimal example (e.g., CodeSandbox) and check if the problem persists with the default Refine data providers and table setup. For more details, see the official documentation and related issues: - Ant Design useTable Pagination - useList Pagination - Related GitHub Issue If you provide a reproducible example, it will be easier to pinpoint the exact cause. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
