Hi @chachi. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To filter an Ant Design table for null values in a DateTime column using NestJS-Query with refine, you can use the useTable hook along with the FilterDropdown component. However, there are some considerations and potential limitations to be aware of. 1. First, you'll need to use the useTable hook from @refinedev/antd to set up your table as shown in the documentation (https://refine.dev/docs/examples/table/antd/useTable/). 2. For filtering, you can use the FilterDropdown component provided by @refinedev/antd. This component makes it easy to apply filters from the Ant Design UI without additional configuration (https://refine.dev/docs/ui-integrations/ant-design/introduction/#usage). 3. However, there's a known issue with filtering for null values in refine when using certain data providers. As mentioned in this GitHub issue (https://github.com/refinedev/refine/issues/3417), the Strapi provider doesn't handle null value searches well. While this issue is specifically about Strapi, it highlights a general consideration for null value filtering. 4. For NestJS-Query specifically, there was another issue reported about the nnull operator not working correctly with the Nestjsx Crud provider as discussed here (https://github.com/refinedev/refine/issues/4805). This issue was labeled as a feature request, suggesting that direct support for nnull filtering might not be available out-of-the-box. Given these considerations, here's a potential approach you could try: 1. Use the useTable hook to set up your table. 2. Implement a custom filter using FilterDropdown for your DateTime column. 3. In your filter logic, you might need to handle the null case specially, possibly by checking for an empty string or a specific value that represents null in your setup. Here's a basic example of how you might set up the column with a filter:

import { useTable, FilterDropdown } from "@refinedev/antd";
import { Table } from "antd";

export const YourComponent = () => {
  const { tableProps } = useTable();

  return (
    <Table {...tableProps}>
      <Table.Column
        dataIndex="yourDateTimeField"
        title="Your DateTime Field"
        filterDropdown={(props) => (
          <FilterDropdown {...props}>
            {/* Your custom filter UI here */}
            {/* You might need to handle null values specially */}
          </FilterDropdown>
        )}
      />
    </Table>
  );
};

import { useTable, FilterDropdown } from "@refinedev/antd";
import { Table } from "antd";

export const YourComponent = () => {
  const { tableProps } = useTable();

  return (
    <Table {...tableProps}>
      <Table.Column
        dataIndex="yourDateTimeField"
        title="Your DateTime Field"
        filterDropdown={(props) => (
          <FilterDropdown {...props}>
            {/* Your custom filter UI here */}
            {/* You might need to handle null values specially */}
          </FilterDropdown>
        )}
      />
    </Table>
  );
};

Remember that the exact implementation will depend on how null values are represented in your specific NestJS-Query setup and how they're handled by your data provider. If you're still having issues after trying this approach, you might need to implement a custom solution or reach out to the refine community for more specific guidance on handling null DateTime values with NestJS-Query. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
