Itertating array data into a Material UI table - reactjs

Question

I am trying to create a table to list all of my users in one go but I am having trouble getting it to display properly.
If I have two arrays to mix in (one of column names and one for where the main array user list should these go inside the return statement? I am stuck at the minute were it is either outputting nothing on a blank screen or throwing this error.
const columns = [
{ field: 'id', headerName: 'ID', width: 70 },
{ field: 'firstname', headerName: 'First name', width: 130 },
{ field: 'lastName', headerName: 'Last name', width: 130 },
{ field: 'userName', headerName: 'Username', width: 130},
{ field: 'userEmail', headerName: 'Email', width: 180 },
{ field: 'userRole', headerName: 'Role', width: 80}
];
const rows = [
{ id: userLists.userID, firstname: userLists.userFirstName, lastName: userLists.userSurname, userName: userLists.username, userEmail: userLists.userEmail, userRole: userLists.userRoleID },
];
return (
<div style={{ height: 400, width: '100%' }}>
{userLists.map(( {}) => {
return <DataGrid rows={rows} columns={columns} pageSize={10} checkboxSelection />
})}
</div>
);
}

Answer 1

you should map your data this way :
const columns = [
{ field: 'id', headerName: 'ID', width: 70 },
{ field: 'firstname', headerName: 'First name', width: 130 },
{ field: 'lastName', headerName: 'Last name', width: 130 },
{ field: 'userName', headerName: 'Username', width: 130},
{ field: 'userEmail', headerName: 'Email', width: 180 },
{ field: 'userRole', headerName: 'Role', width: 80}
];
const rows =userLists.map(user=>({ id: user.userID, firstname: user.userFirstName, lastName: user.userSurname, userName: user.username, userEmail: user.userEmail, userRole: user.userRoleID }));
return (
<div style={{ height: 400, width: '100%' }}>
<DataGrid rows={rows} columns={columns} pageSize={10} checkboxSelection />
</div>
);
}
