useTable only when a parameter is set

I want to display a table only after the user has selected a value from a dropdown: say "entityType". How can I do the call to useTable and then render the table only when "entityType" is set? I'm currently passing the value of "entityType" to useTable as part of the filters.permanent property.

Hi @MesbearizingMeat. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- You can conditionally call the useTable hook and render the table based on the entityType value. Here's a general idea of how you can do it: First, you need to ensure that the useTable hook is only called when entityType is set. You can achieve this by using a conditional statement. Then, you can pass the entityType as a permanent filter to the useTable hook. The filters.permanent property allows you to set a permanent filter state that can't be changed by the setFilters function. Finally, you can conditionally render the table based on whether entityType is set. Here's a simplified example:

import React from "react";
import { useTable } from "@refinedev/core";

export const ProductTable: React.FC<{ entityType: string | null }> = ({ entityType }) => {
    let tableProps = null;
    if (entityType) {
        const { tableQueryResult, pageCount, pageSize, current, setCurrent } = useTable<IProduct>({
            resource: "products",
            filters: {
                permanent: [
                    {
                        field: "entityType",
                        operator: "eq",
                        value: entityType,
                    },
                ],
            },
            pagination: {
                current: 1, 
                pageSize: 10,
            },
        });
        tableProps = { tableQueryResult, pageCount, pageSize, current, setCurrent };
    }

    if (!tableProps || tableProps.tableQueryResult?.isLoading) {
        return <div>Loading...</div>;
    }

    const posts = tableProps.tableQueryResult?.data?.data ?? [];

    // Render your table here using the `posts` data
};

import React from "react";
import { useTable } from "@refinedev/core";

export const ProductTable: React.FC<{ entityType: string | null }> = ({ entityType }) => {
    let tableProps = null;
    if (entityType) {
        const { tableQueryResult, pageCount, pageSize, current, setCurrent } = useTable<IProduct>({
            resource: "products",
            filters: {
                permanent: [
                    {
                        field: "entityType",
                        operator: "eq",
                        value: entityType,
                    },
                ],
            },
            pagination: {
                current: 1, 
                pageSize: 10,
            },
        });
        tableProps = { tableQueryResult, pageCount, pageSize, current, setCurrent };
    }

    if (!tableProps || tableProps.tableQueryResult?.isLoading) {
        return <div>Loading...</div>;
    }

    const posts = tableProps.tableQueryResult?.data?.data ?? [];

    // Render your table here using the `posts` data
};

In this example, useTable is only called when entityType is set, and the table is only rendered when the data is loaded. Please note that this is a simplified example and you might need to adjust it based on your actual use case and the structure of your component. For more information on how to use the useTable hook, you can check the Refine documentation (https://refine.dev/docs/data/hooks/use-table/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
