console.log('Cell render called');

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:
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).

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

@kapa.ai can you provide a full implementation of this
cell: ({ getValue }) => {
console.log('Cell render called');
return statusLabels[getValue()] || "Unknown";
},
Given that feedback

Certainly! Below is a full implementation of the
cell
function using useCallback
to ensure it is not redefined on every render. This will help avoid unnecessary re-renders and adhere to the Rules of Hooks.
Full Implementation
Explanation
1. Memoizing the Cell Render Function:
- The memoizedCellRender
function is defined using useCallback
to ensure it is not recreated on every render.
- This function logs a message to the console and returns the appropriate status label based on the value retrieved by getValue
.
2. Defining Columns with useMemo
:
- The columns
array is defined using React.useMemo
to memoize the columns configuration, which includes the memoizedCellRender
function for the cell
property.
3. Using useTable
:
- The useTable
hook is used to get the necessary methods and properties for rendering the table, such as getHeaderGroups
and getRowModel
.
4. Rendering the Table:
- The table is rendered using the data and methods provided by useTable
, ensuring that the memoizedCellRender
function is used for rendering the cells.
By following this implementation, you ensure that the cell
function is not redefined on every render, which helps in optimizing the performance of your React component.
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).

Can you do the same for this one
cell: ({ getValue }) => {
const skillId = getValue();
const href =
/apps/builder/edit/${app_id}/skills/${skillId}
;
return (
<Group spacing="xs" noWrap>
<a href={href} className="gradient_anim_btn" style={{ textDecoration: 'none', display: 'inline-block' }}>
Edit
</a>
</Group>
);
},

Last one can you do it for the filter function too
cell: memoizedStatusCellRender,
meta: {
filterElement: function render(props: FilterElementProps) {
return (
<Select
{...props}
{...statusOpts}
/>
);
},
filterOperator: "eq",
},
