I have this scrollable table and notice that it only move its tbody not its thead and that's how it should be, but the scrollbar is inside the table which makes the thead and the tbody disarrange, so I had an idea to move the scrolllbar to outside the table, but I don't know how to do it to a scrollbar. Can you tell me how I can do it?

function removeClassName(elem, className) {
  elem.className = elem.className.replace(className, "").trim();
}

function addCSSClass(elem, className) {
  removeClassName(elem, className);
  elem.className = (elem.className + " " + className).trim();
}

String.prototype.trim = function() {
  return this.replace(/^\s+|\s+$/, "");
};

function stripedTable() {
  if (document.getElementById && document.getElementsByTagName) {
    var allTables = document.getElementsByTagName('table');
    if (!allTables) {
      return;
    }

    for (var i = 0; i < allTables.length; i++) {
      if (allTables[i].className.match(/[\w\s ]*scrollTable[\w\s ]*/)) {
        var trs = allTables[i].getElementsByTagName("tr");
        for (var j = 0; j < trs.length; j++) {
          removeClassName(trs[j], 'alternateRow');
          addCSSClass(trs[j], 'normalRow');
        }
        for (var k = 0; k < trs.length; k += 2) {
          removeClassName(trs[k], 'normalRow');
          addCSSClass(trs[k], 'alternateRow');
        }
      }
    }
  }
}

function calcTh() {

  var table = document.getElementsByTagName(table);
  for (var i = 0; i < table.length; i++) {
    table[i].width = (100 / table.length) + "%";
  }
}

function calc() {
  var table = document.getElementById("Stable");
  var w = table.offsetWidth; //total width of the table

  for (var y = 0; y < table.rows.length; y++) { // cycle through rows
    var row = table.rows[y];
    for (var x = 0; x < row.cells.length; x++) { // cycle through cells
      var cell = row.cells[x];
      cell.style.width = (w / row.cells.length) + "px"; // add 'px' for a unit
    }
  }
}

window.onload = function() {
  stripedTable();
  calc();
};
window.onresize = function() {
  stripedTable();
  calcTh();
  calc();
};

I have this scrollable table and notice that it only move its tbody not its thead and that's how it should be, but the scrollbar is inside the table which makes the thead and the tbody disarrange, so I had an idea to move the scrolllbar to outside the table, but I don't know how to do it to a scrollbar. Can you tell me how I can do it?

This achieves the correct effect for me:

html>body div.tableContainer table {
  width: calc(100% - 16px);
  overflow: visible;
}

.html>body tbody.scrollContent {
  width: calc(100% + 16px);
}

However, it assumes that the scrollbar is 16px wide, which may vary among browsers.
