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 (
         <div>
            <h1>React Dynamic Table</h1>

Tôi biết nó khá đơn giản, nhưng hướng dẫn này dành cho người mới bắt đầu và người mới bắt đầu nên biết cách thực hiện loại công việc này., Ý bạn là giả sử bạn muốn tạo bảng 3 × 4? Tôi không thực sự chắc chắn nhưng bạn có thể lưu trữ số hàng và số cột thành biến và dựa vào đó tạo bảng. , cách thêm tìm kiếm và sắp xếp trong bảng

Comment créer une table dynamique dans React

Dans cet article, je vais essayer d'enseigner comment créer un tableau dynamique en réaction. Oui, je sais que c'est assez simple, mais ce tutoriel est destiné aux débutants et un débutant devrait savoir comment faire ce genre de choses., Vous voulez dire, disons que vous voulez générer une table 3 × 4 ? Je ne suis pas vraiment sûr, mais vous pouvez stocker des numéros de lignes et de colonnes dans une variable et en fonction de cela, générer le tableau. ,comment ajouter la recherche et le tri dans le tableau

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: 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.
