My HTML table is with pagination, and I want to download the whole table rather than the current visiable rows

Question

Am new to exporting html table to csv. The code below could export only the current visible page, but I want to be able to download from pages 1 -- 200 for instance at a click of a button.

// download html table to csv file
function downloadCSV(csv, filename) {
  var csvFile;
  var downloadLink;

  csvFile = new Blob([csv], {
    type: "text/csv"
  });

  downloadLink = document.createElement("a");
  downloadLink.download = filename;
  downloadLink.href = window.URL.createObjectURL(csvFile);

  downloadLink.style.display = "none";

  document.body.appendChild(downloadLink);

  downloadLink.click();
}

function exportTableToCSV(filename) {
  var csv = [];
  var rows = document.querySelectorAll("table tr");

  for (var i = 0; i < rows.length; i++) {
    var row = [],
      cols = rows[i].querySelectorAll("td, th");
    for (var j = 0; j < cols.length; j++)
      row.push(cols[j].innerText);

    csv.push(row.join(","));
  }
  //download csv file
  downloadCSV(csv.join("\n"), filename);

}
