To use the FileSaver.js library, you need to create a blob object containing the table data and pass it to the saveAs function.

const FileSaver = require('file-saver');

// get the HTML table data
const tableData = document.getElementById('myTable').innerHTML;

// create a blob object containing the table data
const blob = new Blob([tableData], { type: 'application/vnd.ms-excel' });

// save the blob to a file
FileSaver.saveAs(blob, 'myFile.xlsx');
