Как отсортировать таблицу по горизонтали

var $tableRows = $('#myTable tr');
var preloadData = $tableRows.first().find('td').map(function(index){
  return {
    product: $tableRows.eq(0).find('td').eq(index).html().trim()
    , price: parseInt($tableRows.eq(1).find('td').eq(index).html().trim(), 10)
    , originCountry: $tableRows.eq(2).find('td').eq(index).html().trim()
  }
}).get();

$(document).on('click', '#myTable tr', function(e){
  var sortDesc = e.target.classList.contains('asc');
  var sortingRow
  
  if (e.target.innerHTML === 'Product') {
    sortingRow = 0;
    
    preloadData.sort(function(a, b){
      if (sortDesc) return b.product.localeCompare(a.product);
      
      return a.product.localeCompare(b.product);
    });
  } else if (e.target.innerHTML === 'Price($)') {
    sortingRow = 1;
    
    preloadData.sort(function(a, b){
      if (sortDesc) return b.price - a.price;
      
      return a.price - b.price;
    });
  } else {
    sortingRow = 2;
    
    preloadData.sort(function(a, b){
      if (sortDesc) return b.originCountry.localeCompare(a.originCountry);
      
      return a.originCountry.localeCompare(b.originCountry);
    });
  }
  
  $('#myTable').html(
    preloadData.reduce(function($rows, columnData, index){
      if (index < 1) {
        $rows.eq(0).append('<th>Product</th>');
        $rows.eq(1).append('<th>Price($)</th>');
        $rows.eq(2).append('<th>Origin Country</th>');
        
        if (!sortDesc) $rows.eq(sortingRow).find('th').addClass('asc');
      }
      
      $rows.eq(0).append('<td>'+ columnData.product +'</td>');
