Cell render being constantly updated in useTable columns

cell: ({ getValue }) => { console.log('Cell render called'); return statusLabels[getValue()] || "Unknown"; },

Hi @Matt. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To address the issue of the cell render function being constantly updated in useTable columns, you can ensure that the function is not redefined on every render. This can be achieved by defining the function outside of the component or by using useCallback to memoize the function. Here is an example of how you can use useCallback to memoize the cell render function:

import React, { useCallback } from 'react';
import { useTable } from '@refinedev/core';

const statusLabels = {
  1: "Active",
  2: "Inactive",
  // Add other status labels as needed
};

const MyComponent = () => {
  const columns = React.useMemo(() => [
    {
      id: "status",
      accessorKey: "status",
      header: "Status",
      cell: useCallback(({ getValue }) => {
        console.log('Cell render called');
        return statusLabels[getValue()] || "Unknown";
      }, []),
    },
    // Add other columns as needed
  ], []);

  const {
    getHeaderGroups,
    getRowModel,
    // Other necessary hooks and methods
  } = useTable({ columns });

  return (
    <table>
      <thead>
        {getHeaderGroups().map((headerGroup) => (
          <tr key={headerGroup.id}>
            {headerGroup.headers.map((header) => (
              <th key={header.id}>
                {header.isPlaceholder ? null : flexRender(header.column.columnDef.header, header.getContext())}
              </th>
            ))}
          </tr>
        ))}
      </thead>
      <tbody>
        {getRowModel().rows.map((row) => (
          <tr key={row.id}>
            {row.getVisibleCells().map((cell) => (
              <td key={cell.id}>
                {flexRender(cell.column.columnDef.cell, cell.getContext())}
              </td>
            ))}
          </tr>
        ))}
      </tbody>
    </table>
  );
};

import React, { useCallback } from 'react';
import { useTable } from '@refinedev/core';

const statusLabels = {
  1: "Active",
  2: "Inactive",
  // Add other status labels as needed
};

const MyComponent = () => {
  const columns = React.useMemo(() => [
    {
      id: "status",
      accessorKey: "status",
      header: "Status",
      cell: useCallback(({ getValue }) => {
        console.log('Cell render called');
        return statusLabels[getValue()] || "Unknown";
      }, []),
    },
    // Add other columns as needed
  ], []);

  const {
    getHeaderGroups,
    getRowModel,
    // Other necessary hooks and methods
  } = useTable({ columns });

  return (
    <table>
      <thead>
        {getHeaderGroups().map((headerGroup) => (
          <tr key={headerGroup.id}>
            {headerGroup.headers.map((header) => (
              <th key={header.id}>
                {header.isPlaceholder ? null : flexRender(header.column.columnDef.header, header.getContext())}
              </th>
            ))}
          </tr>
        ))}
      </thead>
      <tbody>
        {getRowModel().rows.map((row) => (
          <tr key={row.id}>
            {row.getVisibleCells().map((cell) => (
              <td key={cell.id}>
                {flexRender(cell.column.columnDef.cell, cell.getContext())}
              </td>
            ))}
          </tr>
        ))}
      </tbody>
    </table>
  );
};

In this example, the cell function is memoized using useCallback, which ensures that the function is not recreated on every render, thus preventing unnecessary updates. For more information on using useTable and customizing columns, you can refer to the refine documentation (https://refine.dev/docs/packages/tanstack-table/use-table#sorting). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

kapa.ai•2y ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The warning you're encountering, "Do not call Hooks inside useEffect(...), useMemo(...), or other built-in Hooks," indicates that you are violating the Rules of Hooks in React. Hooks should only be called at the top level of your React function, not inside loops, conditions, or nested functions. To resolve this issue, ensure that all your hooks are called at the top level of your functional component. Here is an example of how you might refactor your code to comply with the Rules of Hooks: Example Refactor If you have something like this:

useEffect(() => {
  useSomeHook(); // This is incorrect
}, []);

useEffect(() => {
  useSomeHook(); // This is incorrect
}, []);

You should refactor it to:

const someValue = useSomeHook(); // Call the hook at the top level

useEffect(() => {
  // Use someValue inside the effect
}, [someValue]);

const someValue = useSomeHook(); // Call the hook at the top level

useEffect(() => {
  // Use someValue inside the effect
}, [someValue]);

Specific Case in useMemo If you are using hooks inside useMemo, you should refactor it similarly. For example:

const memoizedValue = useMemo(() => {
  const someValue = useSomeHook(); // This is incorrect
  return computeSomething(someValue);
}, []);

const memoizedValue = useMemo(() => {
  const someValue = useSomeHook(); // This is incorrect
  return computeSomething(someValue);
}, []);

Refactor it to:

const someValue = useSomeHook(); // Call the hook at the top level

const memoizedValue = useMemo(() => {
  return computeSomething(someValue);
}, [someValue]);

const someValue = useSomeHook(); // Call the hook at the top level

const memoizedValue = useMemo(() => {
  return computeSomething(someValue);
}, [someValue]);

Relevant Information from Knowledge Sources From the knowledge sources provided, there are relevant examples and explanations about the correct usage of hooks: 1. Issue with useMemo in Documentation: - The issue #2339 (https://github.com/refinedev/refine/issues/2339) mentions that React.useMemo should not be placed outside of the React component and should be correctly placed under other hooks and before the return statement. 2. Issue with useEffect and useMemo: - The issue #3089 (https://github.com/refinedev/refine/issues/3089) discusses a similar problem where hooks were incorrectly used inside useMemo, leading to warnings. By ensuring that all hooks are called at the top level of your React function, you can avoid these warnings and adhere to the Rules of Hooks. For more detailed information, you can refer to the React documentation on the Rules of Hooks (https://reactjs.org/docs/hooks-rules.html). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Using useTable: - The useTable hook is used to get the necessary methods and properties for rendering the table, such as getHeaderGroups and getRowModel. 4.
