Как создать динамическую таблицу в React

В этой статье я постараюсь научить создавать динамическую таблицу в React. Да, я знаю, что это довольно просто, но этот урок предназначен для новичков, и новичок должен знать, как это сделать. Вы имеете в виду, что, скажем, вы хотите создать таблицу 3 × 4? Я не совсем уверен, но вы можете хранить номера строк и столбцов в переменной и на основе этого создавать таблицу. , как добавить поиск и сортировку в таблицу

import React, { Component } from 'react'

class Table extends Component {
   constructor(props) {
      super(props) //since we are extending class Table so we have to use super in order to override Component class constructor
      this.state = { //state is by default an object
         students: [
            { id: 1, name: 'Wasif', age: 21, email: 'wasif@email.com' },
            { id: 2, name: 'Ali', age: 19, email: 'ali@email.com' },
            { id: 3, name: 'Saad', age: 16, email: 'saad@email.com' },
            { id: 4, name: 'Asad', age: 25, email: 'asad@email.com' }
         ]
      }
   }

   render() { //Whenever our class runs, render method will be called automatically, it may have already defined in the constructor behind the scene.
      return (
