Here’s my view:

Upload CSV file.
Import CSV 
		<table id="tbl-data" class="table table-responsive table-striped table-bordered mt-3" class="display" style="width:100%">

And here’s my js:
let btn_upload = document.getElementById(‘btn-import-csv’).addEventListener(‘click’, ()=> {

		Papa.parse(document.getElementById('upload-csv').files[0], {
			download: true,
			header: false,
			complete: function(results) {
				console.log(results);
				
				let i = 0;
				document.getElementById('upload-csv').value = ''
				results.data.map((data, index)=> {
					if (i === 0) {
						let table = document.getElementById('tbl-data');
						generateTableHead(table, data);
					} else {
						let table = document.getElementById('tbl-data');
						generateTableRows(table, data);
					}
					i++;
				});
				
			}
		});
	});

function generateTableHead(table, data) {
let thead = table.createTHead();
let row = thead.insertRow();
for(let key of data) {
let th = document.createElement(‘th’);
let text = document.createTextNode(key);
th.appendChild(text);
row.appendChild(th);
}
}

	function generateTableRows(table, data) {
		let newRow = table.insertRow(-1);
		data.map((row, index)=> {
			let newCell = newRow.insertCell();
			let newText = document.createTextNode(row);
			newCell.appendChild(newText);
		});
	}
