I want to create this table shown in image below. When Click on edit button It should change to textfield and pressing on confirm button it should again transform to tr td tags.

here is my code for the same. I have created Array of objects in which i have id property, name property and value property. On edit button click, it should change to textfield and on confirm button click the value of textfield should update in array of objects.

import React, { useState } from "react";
import style from "./css/Register.module.css";
import { Table, Button, Icon, TextInput } from "react-materialize";

const ManipulateRegister = () => {
  const [RegisterData, setRegisterData] = useState([
    {
      id: 0,
      name: "W Register",
      value: 0,
      isEdit: false,
    },
    {
      id: 1,
      name: "Z Register",
      value: 0,
      isEdit: false,
    },
    {
      id: 2,
      name: "B Register",
      value: 0,
      isEdit: false,
    },
    {
      id: 3,
      name: "C Register",
      value: 0,
      isEdit: false,
    },
  ]);

  const handleRegisterEditBtn = (register) => {
    var datas = RegisterData;
    datas.forEach((data) => {
      if (data.id === register.id) {
        data.isEdit = true;
      }
    });
    console.log(datas);
    setRegisterData(datas);
  };

  return (
    <div className={style.addressWrapper}>
      <div className={style.addressTableWrapper}>

            {RegisterData.map((register) => (

You mutating the same reference, you need to render a copy or the component won't render (shallow comparison):

const handleRegisterEditBtn = (register) => {
  const datas = RegisterData.map((data) =>
    data.id === register.id ? { ...data, isEdit: true } : data
  );
  setRegisterData(datas);
};

Or just change to:

setRegisterData([...datas])
