Prime react data table backend pagination with lazy loading

While employing PrimeReact, I encountered challenges related to the backend pagination of their data table. During these instances, I resorted to employing front-end pagination as a workaround. However, I have since developed a streamlined solution for backend pagination using my custom functions. The PrimeReact documentation lacked clarity on fetching data with a personalized style, prompting me to construct a dedicated function. Below, I outline the step-by-step process for implementing this solution.

*Step 1: Define your necessary states Here, i use my own style *

import data table from prime react into your react component
import {Column} from "primereact/column";
import {DataTable} from "primereact/datatable";

*Step2: fetch data with your UseEffect function *

*Final Step: Show your data into prime react data table *

*Here is my full code : *

`import React, {useEffect, useRef, useState} from "react";
import {Column} from "primereact/column";
import {DataTable} from "primereact/datatable";
import {baseUrl, checkAvailability} from "../../Helper/helper";
import useData from "../../hooks/useData";
import "./Clients.css";

const Clients = () => {
const {token} = useData().store;
const [loading, setLoading] = useState(false);
const {authPermissions} = useData().permissions;
const [first, setFirst] = useState(1);
const [rows, setRows] = useState(12);
const [clientData, setClientData] = useState()
const [totalRecords, setTotalRecords] = useState(0);

useEffect(() => {
    //permination setup
    const IsGetClient = checkAvailability(authPermissions, "get-client-list");
    if (!IsGetClient) {
        return;
    }
    //make a options which i send with fetch function
    const options = {
        method: "GET",
        headers: new Headers({'content-type': 'application/json', Authorization: `Bearer ${token}`}),
    };
    const fetchRange = (page, pageSize) => {
        setLoading(true)
        let pages = (page / pageSize) + 1
        fetch(`https://sltm.selopia.com/api/clients?page=${pages.toFixed(0)}&per_page=${pageSize}`, options).then((response) =>
            response.json()).then(data => {
            console.log(data);
            setClientData(data?.data)
            setTotalRecords(data?.data?.total)
            setLoading(false);
        });
    }

    fetchRange(first, rows);
}, [authPermissions, first, rows]);

return (
    <div>
        <DataTable
            value={clientData?.data}
            lazy
            first={first}
            dataKey="id"
            paginator
            rows={rows}
            totalRecords={totalRecords}
            loading={loading}
            onPage={(e) => {
                setFirst(e.first);
                setRows(e.rows);
            }}
            // rowsPerPageOptions={[10, 20, 50, 100, 200, 500, 1000, 1309]}

            tableStyle={{minWidth: '50rem'}}>

            <Column field="id" header="ID"></Column>
            <Column field="company" header="Company"></Column>
            <Column field="phone_no" header="Phone"></Column>

        </DataTable>
    </div>
);

};
export default Clients;
