making a dynamic table using useState

April 6, 2022

I’m new to javaScript and ReactJS so this might be an obvious question but i can’t figure it out.
Im trying to display my array using useState in a table, as of now i can only display the header.

Also if anyone know how to make this table dynamic i.e adding rows automatically after useState has been updated

import React, { useState, useEffect, Component } from ‘react’;
import Axios from ‘axios’

function Table() {

useEffect(() => {
    Axios.get("http://localhost:3001/api/get/carmodels").then((response) => {
      setCarModelList(response.data)
    })
  }, [])

  const [carModelList, setCarModelList] = useState([])

  const renderTableData = () => {
    return carModelList.map((val) => {
        <tr>
            <td>{val.brand}</td>
            <td>{val.model}</td>
            <td>{val.price}</td>
        </tr>
    

  })
}
return (
    <table id='table'>
    <thead>
        <tr>
          <th>Brand</th>
          <th>Model</th>
          <th>Price</th>
        </tr>
      </thead>
      <tbody>
          {renderTableData()}
      </tbody>
      </table>
    );

}

export default Table

>Solution :

your problem is in renderTableData function it’s not returning jsx here’s the soulution:

const renderTableData = () => {
    return carModelList.map((val) => (
        <tr>
            <td>{val.brand}</td>
            <td>{val.model}</td>
            <td>{val.price}</td>
        </tr>))
}
