I tried from this example but not successfully
Can you please give me example how correctly do this?

added chunk of my code
useEffect(() => {
....
fetch("http://localhost:5000/table/", requestOptions)
.then((response) => response.json())
.then((data) =>
console.log(">>>WIDTH>>>", data.columnResizing); // here is ok - I got for example {name: 255}
setResizeColumns(data.columnResizing); // my own func setResizeColumns
})
....
