Trying to get a functioning react-table this weekend, quite frustrated. I have stripped my project down to the absolute bare bones debugging what is going on, I just don't understand why this is an invalid hook, is there a way I can get better information about what is wrong specifically or am I not reading the error correctly? Errors on running below and all my code at bottom:
react.development.js:209 Warning: Invalid hook call. Hooks can only be called inside of the body of a function component. This could happen for one of the following reasons:
1. You might have mismatching versions of React and the renderer (such as React DOM)
2. You might be breaking the Rules of Hooks
3. You might have more than one copy of React in the same app
See https://reactjs.org/link/invalid-hook-call for tips about how to debug and fix this problem.
(happens twice in console):

I have a functional component PopulateTable.js :
import React, { useMemo } from 'react'
import { useTable } from 'react-table'
import DATA from './data.json'
import { COLUMNS } from './columns'
export const PopulateTable = () => {
const columns = useMemo(() => COLUMNS, [])
const data = useMemo(() => DATA, [])
const tableInstance = useTable({
columns,
data
})
const {
getTableProps, getTableBodyProps, headerGroups, rows, prepareRow
} = tableInstance
return (
<table {...getTableProps()}>
<thead>
{headerGroups.map((headerGroup) => (
<tr {...headerGroup.getHeaderGroupProps()}>
{headerGroup.headers.map((column) => (
<th {...column.getHeaderProps()}>{ column.render("Header") }</th>
))}
</tr>
))}
</thead>
<tbody {...getTableBodyProps()}>
{rows.map((row) => {
prepareRow(row)
return (
<tr {...row.getRowProps()}>
{row.cells.map((cell) => {
return <td {...cell.getCellProps()}>{cell.render("Cell")}</td>
})}
</tr>
)
})}
</tbody>
</table>
)
};
My App.js
import './App.css';
import React, { useState, useRef, useEffect } from 'react'
import 'bootstrap/dist/css/bootstrap.min.css'
import { PopulateTable } from './Component/PopulateTable';
function App() {
return(
<div>
<PopulateTable />
</div>
)
}
export default App;
data.json:
[
{
"1": {
"itemName": "Energy research",
"profitPerHour": 821.6746356364301
},
"2": {
"itemName": "Mining research",
"profitPerHour": 742.7240922619478
},
"3": {
"itemName": "Electronics research",
"profitPerHour": 864.3855853308221
}
}
]
Finally columns.js:
export const COLUMNS = [
{
Header: "Item Name",
accessor: "itemName"
},
{
Header: "Profit Per Hour",
accessor: "profitPerHour"
}
]
What the heck am I doing wrong please all mighty stack overflow gods! I followed the link in the errors, I don't believe I am breaking any rules as far as being #1 inside functional component or #2 must have hooks at top of function.. I followed this
