After installing the Material Table using React JS and mapping the data to it, this error will be displayed on the console while running the application. The reason for this is hard for me to imagine.
Below is the table I developed.
`
const empList = [
{ id: 1, name: "Neeraj", email: 'neeraj@gmail.com', phone: 9876543210, city: "Bangalore" },
{ id: 2, name: "Raj", email: 'raj@gmail.com', phone: 9812345678, city: "Chennai" },
{ id: 3, name: "David", email: 'david342@gmail.com', phone: 7896536289, city: "Jaipur" },
{ id: 4, name: "Vikas", email: 'vikas75@gmail.com', phone: 9087654321, city: "Hyderabad" },
]
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", }
]
<h5>

<MaterialTable
title="Employee Data"
data={data}
columns={columns}
/>
</div>`
So I figured out the solution. If your current version of material table is 2.0.3, just uninstall your version and re-install version 1.69.3. This will solve the issue, it worked for me. They have released the 2.0.3 version quite recently (10 days back) and it seems to have bugs and I guess that's the reason why you and me faced issues.
