How to create a table in ReactJS ?

  • Last Updated : 27 Oct, 2021

In this article, we will create a simple table in React.js just like you would create in a normal HTML project. Also, we will style it using normal CSS. 

Prerequisites: The pre-requisites for this project are:

Creating a React application:

Step 1: Create a react application by typing the following command in the terminal.

npx create-react-app react-table

Step 2: Now, go to the project folder i.e react-table by running the following command.



cd react-table

Project Structure: It will look like the following:

Example 1: Here App.js is the default component. At first, we will see how to create a table using the hardcoded values. Later we will see how to dynamically render the data from an array inside the table. 

Filename: App.js

Javascript




import './App.css';
  
function App() {
  return (
    <div className="App">
      <table>
        <tr>
          <th>Name</th>
          <th>Age</th>
          <th>Gender</th>
        </tr>
        <tr>
          <td>Anom</td>
          <td>19</td>
          <td>Male</td>
        </tr>
        <tr>
          <td>Megha</td>
          <td>19</td>
          <td>Female</td>
        </tr>
        <tr>
          <td>Subham</td>
          <td>25</td>
          <td>Male</td>
        </tr>
      </table>
    </div>
  );
}
  
export default App;

In the above example, we just simply used the HTML table elements which are <table>, <tr>, <th>, and <td> elements. 

Example 2: Now lets us see how we can dynamically render data from an array. Instead of manually iterating over the array using a loop, we can simply use the inbuilt Array.map() method. The Array.map() method allows you to iterate over an array and modify its elements using a callback function. The callback function will then be executed on each of the array’s elements. In this case, we will just return a table row on each iteration.

Filename: App.js

Javascript




import './App.css';
  
// Example of a data array that
// you might receive from an API
const data = [
  { name: "Anom", age: 19, gender: "Male" },
  { name: "Megha", age: 19, gender: "Female" },
  { name: "Subham", age: 25, gender: "Male"},
]
  
function App() {
  return (
    <div className="App">
      <table>
        <tr>
          <th>Name</th>
          <th>Age</th>
          <th>Gender</th>
        </tr>
        {data.map((val, key) => {
          return (
            <tr key={key}>
              <td>{val.name}</td>
              <td>{val.age}</td>
              <td>{val.gender}</td>
            </tr>
          )
        })}
      </table>
    </div>
  );
}
  
export default App;

Filename: App.css Now, let’s edit the file named App.css to style the table.

CSS




.App {
  width: 100%;
  height: 100vh;
  display: flex;
  justify-content: center;
  align-items: center;
}
  
table {
  border: 2px solid forestgreen;
  width: 800px;
  height: 200px;
}
  
th {
  border-bottom: 1px solid black;
}
  
td {
  text-align: center;
}

Step to Run Application: Run the application using the following command from the root directory of the project:

npm start

Output: Now open your browser and go to http://localhost:3000/, you will see the following output:
