How do I get hover effect on rows with material-table react?


I have used material-table with react to render my data. I want to show the hover effect and cursor pointer effect when I hover on rows. But I couldn't find this even in the documentation.

IN SHORT- I want to highlight some colors on a row when the cursor hovers to that row.

Note: I also found a similar question and answer here, but they used another state just to hover which downgrades the performance if I increase the data like thousands rows. Hence it's bad practice so here I am asking for alternate solutions for the same.

Here is my codesandbox link

Below I also pasted my code.

App.js

import React, { useState } from 'react';
import './App.css';
import MaterialTable from 'material-table'

const empList = [
  { id: 1, name: "Neeraj", email: '[email protected]', phone: 9876543210, city: "Bangalore" },
  { id: 2, name: "Raj", email: '[email protected]', phone: 9812345678, city: "Chennai" },
  { id: 3, name: "David", email: '[email protected]', phone: 7896536289, city: "Jaipur" },
  { id: 4, name: "Vikas", email: '[email protected]', phone: 9087654321, city: "Hyderabad" },
]

function App() {

  const [data, setData] = useState(empList)
  const columns = [
    { title: "ID", field: "id", editable: false },
    { title: "Name", field: "name" },
    { title: "Email", field: "email" },
    { title: "Phone Number", field: 'phone', },
    { title: "City", field: "city", }
  ]


  return (
    <div className="App">
      <h1 align="center">React-App</h1>
      <h4 align='center'>Material Table with CRUD operation</h4>
      <MaterialTable
        title="Employee Data"
        data={data}
        columns={columns}
        editable={{
          onRowAdd: (newRow) => new Promise((resolve, reject) => {
            const updatedRows = [...data, { id: Math.floor(Math.random() * 100), ...newRow }]
            setTimeout(() => {
              setData(updatedRows)
              resolve()
            }, 2000)
          }),
          onRowDelete: selectedRow => new Promise((resolve, reject) => {
            const index = selectedRow.tableData.id;
            const updatedRows = [...data]
            updatedRows.splice(index, 1)
            setTimeout(() => {
              setData(updatedRows)
              resolve()
            }, 2000)
          }),
          onRowUpdate:(updatedRow,oldRow)=>new Promise((resolve,reject)=>{
            const index=oldRow.tableData.id;
            const updatedRows=[...data]
            updatedRows[index]=updatedRow
            setTimeout(() => {
              setData(updatedRows)
              resolve()
            }, 2000)
          })

        }}
        options={{
          actionsColumnIndex: -1, addRowPosition: "first"
        }}
      />
    </div>
  );
}

export default App;


Solution

  • add in your inside of your CSS

        tbody tr:hover {
      background-color: blue;
      color: white;
      cursor: pointer;
    }
